Late April 2026 Honeymoon Destination in Central/South America?

Hi there! We just set a wedding date for late April 2026 and are starting to think about where we would like to honeymoon. I'd like something all-inclusive, beachy, relaxing, and with beautiful water. We don't mind a funeral excursion here or there either. We are fluent in Spanish. What would be a destination that doesn't break the bank? Mexico is an obvious choice, but where else is nice at that time of year? Thanks in advance!
