You can buy the VIP ticket from another guy at the pool on Monday where the regular tickets are sold, they have a booth by the pool all day on Monday. I don't know if you can buy the $100 ticket right before the bus leaves, but I know you can get the regular ticket that way. VIP is the way to go!
if i'm asked to go i end up in v.i.p. because of a promo. but i usually end up on the bar.but you need to tip the bartender and server and they will take care of you all night.this is my favorite bar.i might go with the resort,but will make my way to the v.i.p. it's amazing what you can do when you dress in a white tuxedo and fedora to match
