Recommendations for a December Honeymoon?

Hey everyone. My fiancé and I are looking to book our dream honeymoon from the end of December to start of January (6-8 days approximately), and needed some recommendations.

We’re open to all suggestions at this point, but safe to say our budget for this trip would be anywhere from $10k-$15k. We’re looking for a place with beautiful tropical weather (ie. beach, water) that can offer a private villa, good food/clean water, and has nice views beyond the confines of our villa. Because we’re trying to go for 6-8 days, a place that has a diversity of activities would also be a bonus.

Obviously being in December, weather is a big consideration for us as well. We come from cold weather, so want to go somewhere that offers lots of sunshine and good weather (and no monsoons lol) in December.

Open to any tips, suggestions, or ideas!
