Koh Lanta in May?

Hi everyone, 25F doing my first solo trip to Thailand. Been looking into various island hopping routes, and have read that Koh Lanta is a great island for chilling/beach/views without too much of a party scene. However if I go, I’ll be there in early May, and have read this is low season. I’m an introvert but would still like to socialise a bit and eat good food, would Koh Lanta be too quiet? And would it also be possible to get around on a bike? I’m not game enough to try a motorbike. Would appreciate any input, thanks! :)
