Best diving you’ve ever done?

Im turning 30 in February 2026 and I am planning an international trip with friends.

My main criteria are that I want it to be warm (in February), I want to be able to dive in warm water, and I want other good nightlife/experiences for myself and my friends who don’t dive. (ETA when i said “nightlife” I mostly just meant fun things to do. Clubs/bars not necessary)

So I ask, what are your best diving recommendations? Bonus points if they are cheaper to travel to from the US!

ETA I also have a friend who is not from the US and based on his visa status he may not be able to go to the Caribbean. So maybe some places in Europe or Asia would be great to hear too! (I do realize that would likely be more expensive)

TIA!
