If you do want to go to Thailand then Bangkok is the obvious starting point and it’s a wonderful city. You also want to visit Ayutthaya, which you can do on a day trip but it’s better to stay a few days. Chiang Mai is the highlight of the north, partly because it’s insanely cheap and the weather is a bit cooler than Bangkok. Luang Prabang is another town not to miss and it’s fun for at least a few days. Don’t bother spending much time in Vientiane though.
There are always those travelers who celebrate the end of summer and the opportunity to don a sweater and take out the wool scarves and quilted jackets. For them, Iceland would be a perfect destination, with a chance to see the Northern Lights and adorable sled dogs. Montreal is another place with a winter chill, and at the end of the month, you might even find an early Christmas market. San Antonio gets into the holiday spirit at the end of November as well. Sedona offers chilly nights and gorgeous scenery, while Hilton Head Island still enjoys autumn weather and activities.
Congratulations. In order to help you I’d have to know your starting point and also whether you are more interested in cities and culture or beaches and relaxation. November is a tricky month for beaches since it’s a very rainy month in most of the best and cheapest beach areas and islands in the Northern Hemisphere. But if you give me a bit more info I will try to help you the best I can. -Roger
In Central America you could consider Belize. It’s small, but it’s got islands and beaches (not everywhere though) and forests and other cultural sights, and English is more or less the official language. It’s not as well organized as Costa Rica, but it’s not bad and it feels safe. The other to consider there is Panama, which obviously has a lot in common with Costa Rica. It has far fewer adventure activities and the good beaches are spaced out a bit, but still it’s a relatively rich country with tens of thousands of Americans and Canadians living there as well as visiting, so they have a good tourist infrastructure and it’s safe.
Few people travel between Thanksgiving and Christmas—specifically, from the Tuesday after Thanksgiving to the Thursday or Friday before the peak Christmas rush—so you can enjoy substantial savings off peak-season rates (four nights for the price of three, seven nights for the price of five) and your chances of an upgrade are good—if you book through a Caribbean specialist with clout.
From Atlanta, the places that come to mind with the theme of “nature” would be Costa Rica and Belize. Costa Rica is probably the better choice, as it famously has around a third of its land as natural parks. Much of it is jungle, and they have all sorts of activities including zip lining, but also canopy tours and much more. There is also the Arenal volcano there, which is really nice and has some fun hot springs around it. They also have beaches, of course, but there is plenty in the interior of the island to keep you busy. If you know a bit of Spanish, it helps, but most other visitors know little or none.
The hotel rates all over Goa are highest in December and January, but in Anjuna or Vagator they still start at around £10 per night for a private room with ensuite. The cheap places are quite shabby, so it might be worth spending more. Vagator has an amazing beach, but it’s often filled with Russians these days. Anjuna is famous for its beach raves and music scene, but I’ve honestly heard nice things about many other beach areas in Goa.
As you suspected, this is a tricky one. Most of the places that would work for you are having a very rainy month in November, so it’s not a good time. Thailand would actually be a good choice if you can deal with the travel time. The rainy season there ends in October and yet the crowds don’t start appearing until December, so you get low hotel prices with nearly perfect weather. As mentioned, all of the good options in Central or South America have a wet season in November. Argentina could be a good option, as November is late spring there, and it has everything you are looking for. The flights to get there are also fairly long though.
It can still be rainy in Belize in November, so it’s not an ideal time to visit. I quite like Belize and there is a lot to do there, including of course the second largest coral reef in the world. You can also head over the Guatemala border to visit Tikal and even down to Antigua for something different. You don’t get many great beaches there, but aside from that it is great.
As for flight connections, Barcelona and Madrid should have decent connections to Toronto and Delhi, while Casablanca (Morocco’s largest airport) probably does not. So Spain is the better choice by that standard. On the other hand, you can get to Morocco by ferry from Spain in a short time, so you could go to Spain and also visit Morocco for a day or two.
Traveling during the last ten days of December means crowds and exorbitant prices throughout much of the world, but the first two-thirds of the month—before holiday airfares and hotel rates go into effect—can be a serene, value-laden, and just plain lovely time to vacation. Europe is all decked out for the holidays—with locals generally friendly and in high spirits; in the Southern Hemisphere, spring is in bloom; and in the Caribbean, Hawaii, and Mexico, hurricane season is over, the weather is gorgeous, and there are free upgrades galore.
