We also did a package-4 1/2 hours. We made the decision to pay for the drinks upfront, and not get hit with a bill later. For us, and our guest list it worked. Other girls have had good luck going with a Bill on Consumption bar. You really need to know your guests - and what drinks you want to serve. Some mixed drinks, etc aren't included in the package. Your EM can also help you with the decision. I also think it depends on when your wedding is, guests are more likely to drink during an evening reception than a late morning/afternoon reception.
