Honeymoon in Southeast Asia – 10-12 Day Suggestions

Hi, we are getting married in mid-February 2026 and are looking at doing a 10-12 day honeymoon in Southeast Asia. We are adventurous travelers and like to see/do as much as we can so we are not looking to just sit on the beach and be pampered (although a couple days of that would be nice). Ideally, we would go to 3-4 different places for 3-4 days each, with at least one of those places being on the beach

Our budget is $5000-$7500, incl. flights from the central US which is coming out at about $1200 per person RT.

Originally. we were planning on spending all of our time in Thailand, which is still a very viable option, but looking at some of the other countries in the region, we are now interested in Vietnam, Cambodia, The Philippines, almost any country that has surreal scenery/history that you can't see anywhere else.

Looking for opinions/suggestions on this 10-12 day trip! TYIA
