Dd was 9 when we stayed there. She really enjoyed the Volcano Pool, but it tended to get very busy which really prevented her from having a great time. She actually enjoyed the quiet pool also. On a scale of 1-10, I think she would give it an 8...loved the pool/slide but hated the huge line.
We stayed at BWV for the first time in August and she loved that slide!! She did run into lines mid-day but it wasn't as bad as the Volcano Pool line!! ANd she enjoyed the slide more since it doesn't get 'dark'. All in the open.
