its a bit far... the oasis palm beach is at the bridge where the pirate ships are and the oasis... well its kinda really far from there, def not walking distance... but the busses run 24/7. oasis palm beach is closer to the party zone than the Grand
im not sure about grand oasis (meaning the restaurants and stuff) there are two bracelets, the purple and the black one... both of them can get you into Oasis.
