Advice on which beach destination to plan!

Hey, a friend of mine and I (F26, M27) are looking to take a week long trip in may end early june.

Need suggestions for places outside India. Beaches are a must!! Sri Lanka, Thailand have been on the radar for a while but the weather is making me a bit concerned and confused about them. (Warm weather is not an issue particularly) Any suggestions as to what parts of said locations we could cover or some other places that you’d recommend??

Chill vibes, mix of relaxing and some activities/clubs is what we are looking for! Budget not an issue.

Thanks in advance!
