It would be hard to beat Chiang Mai for its combination of great November weather and low prices. Even though it's officially the start of the high season for hotels, the beginning of the month is usually very slow anyway, so bargains are common. Hotels in Chiang Mai are among the best bargains in the entire world, so even if you do have to pay full price for a room it'll be cheaper than a dorm bed in most European cities.
As for Malaysia, I love it there too, but it has very few nice beaches in the main part of the country (not including Borneo). But now that you mention it, they do have some nice beaches in Penang, which is the best tourist area anyway. If you search for hotels in Penang, make sure that they are on or very near a nice beach. Most of the island does not have sandy beaches, but some parts do.
Phuket is incredibly popular among Europeans in December, especially the final week, of course, so it's critical to book early to get a good price at a beachfront hotel if that's your mission. It's also important to mention that Phuket is an island with more than a dozen different beach towns, each with its own personality and price range. Some are raucous and down-market while others are quiet and very expensive.
St. Bart's is a French island and a member of the European Union. First discovered by Columbus in 1493 and named after his brother Bartolomeo, St. Bart's has been populated through the years by native Arawaks, pirates, French colonists, Swedish settlers, and French citizens attracted by the island life. Owned for a time by Sweden before being returned to France, St. Bart's capital, Gustavia, was named for a Swedish king, and the language, along with French, is used for many street signs. In Gustavia, visitors interested in the island’s history can explore 17th-century forts, a lighthouse, and the small Wall House Museum. With 14 public beaches, there’s one for every taste and activity, including a swimsuit-optional spot. Boating, windsurfing, kayaking, sunbathing, shopping, people watching, and exploring the island’s shallow reefs are favorite pastimes. Last September’s Hurricane Irma caused significant damage to the island, but recovery has been swift. After closing a year for renovation, Le Barthelemy Hotel & Spa has just re-opened. Set on the Anse de Grand Cul de Sac, an ideal area for watersports, the eco-friendly hotel emphasizes wellness, with an expansive spa offering hydrotherapy, sauna, and beach yoga. This perfect December island escape is accessible by air or ferry from nearby St. Maarten.
Surprising to some people, December can actually be a bit cool in Mexico City, especially at night. Its elevation keeps it mild all year, but at least the rainy season is totally over by December, so it's an ideal month for a cheap cultural holiday, perhaps combined with a trip to one of Mexico's many beach resorts. You can get cheap flights between Mexico City and Cancun or Puerto Vallarta, for example.
This is a tricky one. Pretty much every destination in the Tropics has its peak rates of the year during the weeks you have in mind. That said, there are still some fairly cheap destinations in the Caribbean, even at peak rates. However, since you live in South Florida and understandably don’t want to go someplace even hotter during the only semi cool time of the year, it sounds like you are ruling out most of the Tropics.
When you mention, “not too touristy”, the first thing that comes to mind is San Juan, Puerto Rico. I’m not sure if you’ve been there already or not, but one great thing about it is that the “tourist” areas close to Old San Juan are filled more with apartments than with hotels, unlike Cancun, where it’s nothing but hotels and timeshares. I can highly recommend the Condado neighborhood, which does have some large hotels but is mostly apartments for expats and seasonal visitors. There is even a free bus that goes from there to the heart of Old San Juan, which is a gorgeous colonial town filled with great restaurants, bars, and interesting attractions.
Trekking in Nepal during peak season might not sound like the most sensible choice for penny-pinching backpackers. But you can still enjoy the ideal weather without spending a fortune on in-demand hotels and expensive permits if you're happy to swap big-name trails, like Everest Base Camp and the Annapurna Circuit, for quieter treks to Kanchenjunga Base Camp and around the Langtang Valley. Idyllic conditions (dry but not witheringly hot) are also on offer in Rajasthan, one of India’s most vibrant and varied states. Chug between notable, attraction-rich cities like Jaipur, Jodhpur and Udaipur on an atmospheric and wallet-friendly Indian train, snacking on spicy pakoras and sipping sugary chai en route.
There is no better time than December to discover a still (somewhat) under-the-radar part of the Caribbean. This verdant, five square mile island has seen a lot of activity recently, from a new mega yacht club to a Soho House to the Mandarin Oriental's first property in the Caribbean. More is on the horizon for this picturesque piece of paradise, but go before everyone else discovers it.
Brazil, on the other hand, has a famous problem with petty crime in tourist areas so I wouldn’t recommend it for a woman and young child. Another to consider is Puerto Rico, which has a lot to offer including great weather, and it’s also more or less part of the US, so it’s fairly safe and well organized. Hotels in Puerto Rico are a bit expensive, but you should be able to get an apartment rental in the San Juan area (gorgeous, by the way) for a modest price if you are staying for more than a few days. Let me know if you have any other questions. -Roger
If intermittent fasting is part of your low-carb routine, use it strategically to skip meals and make travel simpler. Perhaps you rush to your early morning flight and wait to eat until lunch. Or, eat a hearty low-carb breakfast before leaving home and don’t eat again until dinner at your destination. One nice thing about fasting is that you can do it anywhere.
That really depends on your starting point. Most of the cheapest places are in Asia, but the flight would be quite expensive if you are in North America or Europe. If you are in the US, your best bets for cheap places with good weather that time of year will be the non-resort towns of Mexico, or even the resort towns if your budget is a bit higher. Let me know your starting point and more about what you are looking for and I can give you a more complete answer. -Roger
Sri Lanka doesn’t really have a good infrastructure for budget travelers at this point. There are loads of nice hotels if you are willing to pay US$40 or more per night, but almost nothing below that except for a few hostels. I haven’t been to Palawan but I have been to Boracay and Palawan can’t be too much cheaper. Boracay doesn’t have many budget options either, so my guess is that Thailand or Cambodia is your best bet.
