We went to Wbg the second week of June last year. The weather was hot. Not unbearable, but hot.
We stayed at a Days Inn which was a dump, but I think I know the Hampton Inn you are booked at and I remember wishing we were staying there! LOL
There is a Cracker Barrel, a Pizzeria Uno, and a Golden Corral very close to where you are staying, and tons of restaurants not too far down the road.
We did Busch Gardens, Colonial Wbg, and Water Country. We bought the "bounce pass" which was a GREAT deal, even though we only had three full days. It included parking, which made the value even greater.
We also bought the meal vouchers for BG/WC. I don't recommend them. Not a good deal, not remotely close to WDW meal plan.
My family LOVED WC. LOVED IT. We could have done this twice. We went on a day that was not busy, and the weather was perfect. We did not wear water shoes, but wore flip flops to walk from ride to ride. It worked out. My kids loved the Hubba Hubba Highway...we could have stayed there all day long!!
BG was nice, but easily do-able in one day. It was not crowded at all the day we went, so lines were short. I highly recommend seeing the Irish Dance show. It was fantastic!! We were lucky to be chosen to sit up front and center....when you see the show, you'll know what I mean!
Unfortunately, CWbg was a bit of a flop for us. The reinactment stuff in the morning was really good...we all enjoyed that a lot! After a certain time of day, though, there was not much going on. It is a LOT of walking, on gravel. Just sayin. Plan your time out accordingly so you don't keep backtracking. We ate lunch at Chownings Tavern. It was an expensive disappointment. Food was lackluster...sandwiches....nothing special. Cost a small fortune.

The "signature" beer was good though!
All in all, a good vacation. I don't know if we will go back again, but I'm glad we tried it once!
