If you wan to party and make noises i would prefer you to stay in the beach shakes or rent a property all to yourself. Because hotel owners and homestays are somewhat particular about making noises. But in beach shacks you can party in open areas around the shacks. Also locals gives out their homes for rent, if you take that option you will have the whole property to yourself and you can do whatever you want.
