This is a huge question and I’d need to know more about your preferences and your budget to answer it properly. But I can give you a short version here. In my opinion, which is matched by many other people, the most interesting and dramatic cities in Europe are London, Paris, Amsterdam, Rome, and Venice. Visiting those would require about 16 days to do it properly because you’d want to spend 3 or 4 days in each city, except maybe only 2 days in Venice because it’s quite small.
One of the best things about Puerto Vallarta is that, unlike most of the Caribbean destinations, this is a real historic town rather than a purpose-built resort community. That means that there are small and authentic (and cheap) restaurants catering primarily to locals, so you get a much more authentic experience if you prefer one. The hotel zone close to the airport is modern and posh, but you are a short taxi ride away from the lovely center of town.
Once the scorching temperatures and monsoon rains of summer have subsided, November is the perfect time for exploring this kaleidoscope of colour and culture. Due to India’s size and terrain, you can still expect some variation across the country, but travels through Rajasthan and the Golden Triangle will be mostly dry, clear and balmy with a maximum of 30c (86F). Perfect for tiger-spotting in Ranthambhore, camel rides in Pushkar, and admiring the shimmering Taj Mahal!
By early December the rainy season is pretty much over in Cartagena, and it cools down just a bit more as well, so the weather really doesn't get any better than this. As with most others on this list, right around Christmas you'll find that hotels get more expensive and are more crowded, so if you can go earlier in the month you'll be paying less and dealing with fewer crowds.
It is this quintessential destination-- nestled conveniently between Boston and Cape Cod-- that’s known as “America’s Hometown,” offering not just a glimpse into our national history, but an array of enjoyable activities from water sports to golfing to whale watching to ghost tours. During the fall you can even take trolley or culinary tours, or witness live cranberry and pumpkin harvests. It’s a November getaway to remember for sure.
The biggest single highlight in the region is the Angkor Wat temples near Siem Reap in Cambodia. It’s one of the most impressive tourist sights in the entire world, and Siem Reap is a fun and mellow town that you can linger in for a while. Vietnam is really lovely and cheap as well. The food there is excellent, as it’s a fusion of French and traditional Asian. You can go from Ho Chi Minh City in the south on the train to Hoi An near Da Nang, and then up to Hanoi to see Halong Bay. I wouldn’t start in Vietnam because it can be a bit trickier than the others. In the rest of the region it’s easy to book tours and buses and such, but in Vietnam the travel agencies are a bit harder to trust, so you have to be more careful. Things there are very cheap though, so even if you pay more for a reputable agency, it’ll still be cheap.
Located off the coast of East Africa, the Seychelles—an archipelago consisting of 115 islands—is about as close to paradise as you can get. Crystal clear water, lush jungles, and powder-fine sand make it the ultimate early winter escape, particularly for romantic getaways. Book one of the 30 breathtaking pool villas at Six Senses Zil Pasyon, which is among the region's top luxury resorts. The hotel is situated on a private island that offers prime territory for snorkeling, sailing, kayaking, and hiking—plus, the spa has scenic pavilion-style treatment rooms that are worth the trip alone. Health conscious guests will be particularly impressed by the property's new "Eat with Six Senses" program, which is intended to make travelers leave vacation without the guilt that comes with overindulging. There are four tailor-made treatment plans that focus on sleep, detoxing, fitness, and more, depending on the issues you prefer to address.
