The Brazilian currency has been falling in recent years, and if this trend continues then Rio de Janeiro will be squarely back into the bargain category. It's certainly not as cheap as it used to be, but for the amazing beaches and scenery it's easily worth it as long as you plan well and stay safe. In fact, Rio has some of the best beaches in November anywhere in the world, and a vibrant city right next to them.
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.
You might also consider Malaysia and perhaps a stop in Singapore. Malaysia is actually more modern than Thailand so everything is easy and reliable. They have cheap VIP buses that are very comfortable. Penang in the north is really nice and also interesting. Kuala Lumpur is a modern and pleasant big city. A bit south of that is the colonial town of Malacca, which is also very nice and worth a look. Going south from there you can reach Singapore in a few hours, and that is an amazing city, although accommodation there is expensive.
I know Italy is the world’s top wine producer and they obviously make a lot of olive oil as well. I’ve seen on many travel shows how it’s fairly easy to visit the olive oil places, and of course most wineries have places where you can see the process and taste it. The thing is though, that even Sicily is quite chilly in December so they might close down for the season. You definitely won’t get sunbathing weather in December at all. I would say you are best off in May, June, September, and October to get good weather and not have to deal with the insane crowds in July or August. Tuscany is the easiest to reach of the 3, but because of that its beach towns are most likely to be crowded in those warm months. I hope this helps and let me know if you have any other questions. -Roger
I think Spain is probably your best bet, and you can probably get there on a reasonably priced flight with a change in Dubai or Abu Dhabi. The winter weather is decent and the big cities are always packed with locals rather than so many tourists. Barcelona is probably more fun than Madrid, though both are big cities with a lot to see and notoriously good nightlife. If you get a cheap enough flight I don’t think you need to do a package. It’s pretty easy to get around Spain’s big cities just on English, as long as you do a bit of research. In 5 days you could spend 3 days in Barcelona and then 2 days in Madrid, or just 5 days in the Barcelona area. It’s a big city with plenty to see and some good day trips. You could also go to Valencia, which is also really fun and a short train ride away.
Of the others, I’d say that Thailand would probably be your better choice. Goa is obviously famous for its beach parties, and drugs are easily available there just in case that is important, but there really isn’t much else to see or do there. Goa is a collection of beach towns, some of which are filled with raucous Westerners all winter. But once you go inland, it’s kind of falling apart, and it’s not even very “Indian” because it was run by the Portuguese until about 60 years ago.
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.
