hi scuba! i just took a trip with them recently and it was fantastic!we put in like 21 dives or something ridiculous! going as a single won't be a problem as living quarters are tight and you will meet tons of scuba friends. you won't need to bring much though.. few pairs of board shorts, your dive gear, couple of t-shirts and a pair of flip flops you'll be good.. you really won't need to bring a lot because you'll be in the water a ton! the less amount of stuff you bring the happier you'll be because you won't have to carry a bunch of unecessary stuff. essentials though would be sun block, toothbrush-paste, deodorant, and soap and you'll be good! there is a sweet shark dive too! bring a camera for sure!
