Tropical Honeymoon destination ideas in Feb / March?

Hey everyone. My fiancé and I are getting married in October and are looking at planning our honeymoon for late Feb or early March. We’re flexible to any point after that but that’s what we’re thinking and would love some destination ideas.

We’re traveling from New York and looking for somewhere tropical, luxurious, and with a good mix of relaxation and adventure.

We’re open to most places but I think we’d like to choose something other than South America as that’s where my fiance is from and we have been there a bit — as long as the weather’s good that time of year. Prefer somewhere less touristy but still high-end and memorable.

Would love recommendations for destinations, resorts, or itineraries you loved. Thanks for taking the time to read and for any advice!
