The rainy season in Cartagena winds down by early November, so this is an ideal time to come, especially toward the end of the month if you can get cheap airfare before and/or after Thanksgiving. The temperatures are pretty much the same here every day of the year, so the key is to work around the autumn rainy season to when it's dry but before hotels fill up.
Increasingly popular, Lisbon is quite warm in summer, but November’s cooler temperatures and fewer crowds make it a pleasant time to visit. A city of hills and spectacular views, many terraces (miradouros) offer vistas for those who climb (or take a taxi) to the top. Alfama is the city’s historic district, defined by hilly, narrow cobblestone streets. The Fado Museum, in Alfama, honors Portugal’s soulful folk music and provides some background on the sounds heard nightly in the city’s fado houses and bars. Seafood is plentiful in Lisbon, and the traditional Portuguese dried salted cod (bacalhau) is on most menus along with octopus, shrimp, sardines, clams, and tuna.
Costa Rica is kind of the Thailand of Latin America in that they have great tourist infrastructure and it’s the easiest place to get around. They also have a lot to offer with the beaches on both coasts and many natural sights and activities, plus of course the Arenal volcano, which is a really nice area. San Jose is best as a place to just pass through on your way somewhere else.
December might be the only month of the year in the Canary Islands where very few people would consider sunbathing. Still, compared to everywhere else in Europe, Tenerife is balmy. The largest and most English-speaking of the Canary Islands, Tenerife is no mystery to the hundreds of thousands of northern Europeans who spend a month or more here every year.
All of my best suggestions are in the article above, but I’ll try to expand a bit more. The tricky thing, as you probably know, is that November is part of the heavy rain season in most of Thailand and the other popular southeast Asian countries. There are wet months in summer with just short rain storms, but in November it can often be rainy all day.
While the Caribbean destination tends to overflow with families during the holidays in December, go a month earlier and you’ll be treated to sunny days sans screaming kids, plus less expensive airfare. “November is my one my favorite months. The hustle and bustle of high season hasn't kicked in, average temperatures are in the 80’s, and the water temperature is lovely,” says Michael King-Hew, the proprietor of Kamalame Cay, a private island resort in the Bahamas. King-Hew specifically suggests for the resort's annual wellness retreat. “It’s the perfect way to get rested and in shape before the start of the hectic holiday season.”
If you’re a bit more on the timid side, you can always use Yelp and TripAdvisor to get good insights on places people have visited. As a disclaimer, some of the ratings may not be accurate on these sites, so make sure you go through and read some of the more recent reviews that people have written. We did this for a few of the places we visited and had no issues.
