Their selection from what I can remember is your basic/standard conv. store line up.
While we rarely buy or drink alcohol I tend to notice what a store has and what it doesn't - and really if you wouldn't find it at a smaller conv. store near your home - I wouldn't count on that Hess having it either.
However - they have good hot chocolate and cappuccino! When we stayed at AKV last December I went to the Boardwalk Bakery and got cookies and then stopped at HESS to get hot drinks for a late night snack to take back to the room- it was great!
DH and DS love Strongbow, as I do sometimes. DS had it when he did study abroad at Oxford, so every time we go to Epcot they get it at Rose and Crown Pub. We did find it at Target. The one near AKV. From AKV, you go down Sherbet Road take a right at the end and it is a few miles down the road on the left. We just brought some back when we were there in Oct.
