during the day it was free last time i was there. At night you get it with a bottle. might be able to buy it separate as well? They wouldnt even sell me a bottle last time i was there as It was just the wife and myself and they won't sell it unless you have 3 people.

YR isn't my favorite spot for extras as their cabanas aren't private and are overpriced. (they are rather well lit and in full view of the entire VIP section)
