Mauritius would be an interesting option if you wanted to mainly stay in one place, which I think is typical on a honeymoon. Sri Lanka is fascinating and really nice, though most people who visit tend to tour around seeing some beach areas and some of the hills and jungles. So I’m not sure if it’s ideal if you want to just stay in one place. Kerala has some really nice resorts that are within easy reach of the backwater boat tours and other attractions.
However, I would probably recommend staying closer to the US, unless you are really interested in the Asian cultures or that kind of experience. If you are mainly just interested in family time and a fairly easy holiday for all, and you aren’t specifically interested in getting to know an Asian culture and its food, I think I’d stay in the Americas.
Hotel prices definitely go up in around Christmas so it's best to come early in the month if that's possible, but it's still a pretty good bargain even during the peak weeks. Book early if you can because the better and cheaper hotels will fill up first, of course. Also consider a side trip to the Mendoza wine region, Patagonia, or the amazing water falls of Iguazu.
The other place that comes to mind is Croatia, which also has reasonable weather in November. I’d recommend focusing on Split, which has many similarities with the more-famous Dubrovnik, but it’s easier to reach, much cheaper, and more authentic because Dubrovnik has become kind of cheesy as a cruise port. You could even take a bus to Mostar or Sarajevo in Bosnia for a couple days. The coast in that area is beautiful and there won’t be many other tourists that time of year. I hope these ideas help. Let me know if you have any other questions. -Roger
Oh no. I don’t mind rain but that would be a little disheartening. I come from a tropical place and it wasn’t until I moved to Canada that I realized that “rainy seasons” don’t really mean much. More so, I went to Punta Cana last October during the cold period and it was gorgeous every day, and what little rain fell was usually overnight or little drops that you could stay on the beach unbothered.
The Bali thing is also kind of a mess for those on low budgets. Kuta is a headache, and pretty much the opposite of what is so beautiful about the rest of the island, but it’s also where nearly all the really cheap beds are located. If you go a bit north in that same area into Legian and Seminyak, it’s nicer, but prices also go up. And Ubud is nice, but also more expensive for hotels and such. I’ll probably rent a place in Seminyak for a few weeks, which won’t be cheap.
Really my first bit of advice is that the best place to get a really nice hotel that is on a beach or a hill and has the other nearby and also has great weather in December is Phuket, Thailand. You could go almost anywhere in southeast Asia in December and get good weather and low prices. But Phuket has over 1,000 hotels and hundreds of those are wonderful fairly luxurious hotels or villa complexes that could be perfect for a romantic honeymoon stay.
Regarding Thailand, I’m not familiar with any islands that are beautiful and not touristy. Phuket has beaches all over the island and many of them are isolated so the only guests are those staying at the resort in front of them. If you search other travel sites, including travelfish.org, which I think is the best site for southeast Asia and it’s run by a friend of mine, you can find more information about more obscure Thai islands. One challenge could be that you might have to take two or three total flights and then a ferry ride to reach them.
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.
