Two islands : Can anyone assist ?

few years ago I visited Bangkok, Bangkok, Krabi, Phuket.  We went on a boat to two islands in the middle of the ocean. There was a bar, music, food. I cant remember where we departed or what the islands are named or the name of the cruise. Can anyone assist.

Phi Phi Island perhaps?

That's not much to go on it describes about a dozen islands. Do you recall which

port you departed from? How long was the boat ride?
