I stayed at POP and they had a pool bar, if I recall. I know it had beer and maybe daquaris and maragritas. I don't know if they have a full bar. Also the food court sells beer and wine to take to your room.
I am quite certain that WL will have a full bar, pool bar, and food court with alcohol.
FYI- Depending if you are driving. We always bring a cooler of drinks with us. Since you spend so much money as it is, you can at least save some money bringing your own drinks. Or if you are flying and have a rental car, a short drive to the grocery for beer run is wise.
We will be staying at CSR without a car. Using ME to get from airport. Does the cost of the beer and wine in the shop at resort justify the expense of a taxi or rental car to make a grocery run?
wegoshop is an interenet delivery service for groceries and beverages. it is a good option for those who want sancks or beverages in their resort villa or room
