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.
If you are looking for something far less developed than Phuket or any other Thai island, Boracay might be for you. This gorgeous strip of sand is a bit out of the way, but partly because of that it still feels only partly discovered. You'll spend your days relaxing along White Beach or walking up and down the sandy paths that serve as the only real form of transport for most people. Many visitors come every year, and quite a few of those never seem to leave.
I a from India, Me and and wife plan to go for a quick 4-5 days holiday with an infant who is just 6 mpnths old. so we cannot take long flights, we cannot go to places which are very crowded and hustling and bustling. We want a relaxed holiday where we can take time out and enjoy in true sense. Cannot go to a very cold plave aginst with an infant wont be right. We have been to Thailand( phi phi and kho samui) dubai, bali, singapore, sri lanka already.
November can be an ideal month to visit Boracay Island, even though you'll probably see a few quick rainstorms each week. This stunning and laid-back island is in the Tropics, so you can get a quick cloudburst a few times a week this time of year, but they are easy to avoid and the sunsets that form as the clouds are leaving again are often so gorgeous that it's all worth it.
Those temples are all outdoor for the most part, so cooler and dryer conditions mean you can spend more time touring the temples and still being comfortable. Almost any other month of the year and you'll be better off going back to your hotel for a few hours in the afternoon, but in December you can carry on all day if you like. The town of Siem Reap is a delight in itself, but of course it fills up near Christmas.
Another destination that might not exactly have “great” weather in December, yet deserves to be on the list, Sharm el-Sheikh is famously Egypt's most popular Red Sea beach resort. Those following the news might still hesitate to book a trip here, whether that is a rational decision or not. But at the very least this is one to consider in the future, as it's an amazing bargain once you get here.
The rainy season is still finishing during November in Central America, but a bit north and south of that it's dry enough to make visiting very worthwhile. Better yet, it's still low season for hotels in most places even though the weather has gotten nice. Latin America is filled with excellent bargain choices and it has some of the best places to visit in November.
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.
