So long story short, if you want to visit Istanbul and perhaps another city, I think December could be okay. But for almost anywhere else in Turkey I just don’t think it’s worth it. Fortunately there are plenty of other places to choose from and hopefully you can find time for Turkey another time of the year. Let me know if you have any other questions. -Roger
The best places in December with good weather and that are inexpensive and also fairly close to India are Sri Lanka and Thailand, and they are both mentioned in the article above. Sri Lanka is obviously closer and you have many nice and scenic areas in the hills as well as the beach areas along the southern coast. But Sri Lanka has many similarities to India, as you may know.
But again, Vietnam can be a bit complicated for first-timers. Specifically, you need to book trains and tours through travel agencies, and Vietnam’s many travel agencies have a worldwide reputation for being hard to trust. They are all great salespeople but the product they deliver isn’t always what you expected. I spent 4 months in Vietnam and loved most of it, though I think it was much easier as a solo traveler who didn’t have a set schedule.
If you are going for one week I wouldn’t go all the way to Thailand, but if it’s two weeks I think it’s worth it. It takes most of a day in each direction, but flights are often reasonably priced, and everything there is cheap once you get there. I’ve actually lived in Thailand for 6 months and have visited many more times and it’s actually very easy and stress free once you are there. All the important signs are in English and nearly everyone you’ll encounter as a tourist will speak enough English to help you as well. You can get around by train or VIP bus for cheap, or fly to the islands for cheap. It’s very safe there as well. You could spend a few days in Bangkok and then head to one of the islands or take a train up to Chiang Mai.
As Christmas approaches the city will fill up much more, so if you can go early in the month you'll be much better off. But even if you can't go before the last week of the month you'll still find Mexico City to be a tremendous bargain compared to pretty much anywhere else in North America. It's a great shopping destination, and not just for goofy souvenirs, so that's something to think about as well.
My best recommendation would be somewhere in the islands of Thailand. December has very pleasant weather with warm days and nights that can be a bit chilly (for some people). Best of all, it’s a very beautiful place and the tourist infrastructure makes it easy to get around speaking English and with very few headaches. The largest island is Phuket and it has famous nightlife in the Patong Beach area. In fact, the nightlife is so notorious that many people think it’s too much so they avoid the place. There are many other beach areas that are quiet and still close enough to go into Patong once in a while.
Another reason to consider Dubai is that the busy airport has cheap non-stop flights coming in from almost every major airport in Europe and Asia. As a result it's popular to book long weekend trips of 3 or 4 days to Dubai, where you can enjoy some sunshine and shopping before flying back home where it gets colder by the day. You might also consider stopping for a few days in Dubai and then moving onto somewhere else with cheap direct flights such as the Maldives.
Hmmm…this is a tricky one. Since you want to get out of SEA, you might have to go a long way to reach someplace that could be considered cheap and also has decent weather in December. Japan and South Korea will be cold, and not really cheap. If you go south you hit Australia, which is very expensive by most SEA standards (although not bad by Singapore standards). Perth is obviously closest and it’s a real city, and of course Sydney and Melbourne will be in early summer in December so those could work if your budget allows. Brisbane and Cairns are both known for outdoor activities, although nightlife might be tough for teenagers and there are no real cultural sights.
Later in the month, the day after Thanksgiving begins Christmas season with the Ford Holiday River Parade and Lighting Ceremony. Decorated floats wind through the illuminated trees and bridges along the river. Luminaria, San Antonio’s annual free contemporary arts festival (Nov. 10-11) will take place in Hemisfair and other downtown venues, unveiling a special program at the Mission San Jose, a UNESCO World Heritage Site. San Antonio has been recognized as a Creative City of Gastronomy by UNESCO’s Creative Cities Network. Influences of Mexican, Spanish, German, French, and Native American cuisine and ingredients combine to form the city’s culinary heritage, increasingly attracting foodies to its hundreds of unique restaurants.
Being from Mumbai you can be forgiven for not realizing how unappealing beach areas are when the air temperatures are only a bit above freezing. Seriously, even beach on the European mainland is totally deserted by November 1, and many of the local hotels and restaurants are closed by then until April or so. Now, if you are mainly after the novelty of being on a beach in the European winter, you can certainly go and still find open hotels and restaurants. If I had to recommend one place to consider it would be Spain’s Costa del Sol, which is the resort area around Malaga. The average high in December in Malaga is 17, and the average low is 8. You’d be the only one on the beach, which might be kind of nice. It’ll also probably be windy. If you were going to do that I’d recommend staying in Malaga itself, which does have a nice beach area in the city, and since it’s a city the hotels and restaurants will all be going.
If you really want to see the city up close, visit in November or December, when the crowds have dispersed. Hotel prices are comparatively low, and gondoliers are more appreciative of customers. And once you have your fill of religious art, head for the Peggy Guggenheim museum, which displays 20th-century American and European art in a home and garden setting. Note: October through January is the time of acqua alta, when Venice may flood. Usually it's not severe, and the city puts up wooden walkways for visitors and residents to traverse the water.
Since flights to Mexico City from the US and Canada are usually quite cheap this time of year as well, this could be a perfect short cultural holiday. This city has great shopping, dining, and nightlife, and the central historic and tourist districts are far safer than most people would expect. There are ruins just out of town as well, so a bit of everything is available.
