Hawaii and Fiji are both gorgeous, but are really Long flights. If you have under 2 weeks I would choose somewhere else.

Bermuda is awesome. It is a very quick flight and has hiking history gorgeous beaches, snorkling etc.Bere are no snakes on the entire island.

Anguilla is also very nice.. Remote not very touristy, plenty of deserted beaches to explore,no crime. You can also take a boat from there to St Barts.

Puerto Rico is beautiful... as is jamaica... but you need to be a bit careful.

Aruba is very touristy in my opinion.

Have fun Wherever you go!
