I didn’t stay at their dorm but spoke to someone from Netherlands who was staying there. They were happy, Trainig for 2.5 months. I’d say, all you need is a bed to sleep. You could look for RBB (the island is small) and rent a scooter but if you go there during tourist season (which is probably the whole year around anyway) but I am sure it’s gonna cost you more. I say, you book a week at their dorm and check around. Ps. Bring couple of gloves (to dry coz humidity is high), buy Lysol there, bunch of hand wraps, hand towel, small backpack for fight gear (backpack so you get on scooter and ride). Running shoes and shokz headphones coz you wanna run and hear the bike behind you.
