I guess you can't please everyone but I think BG is an excellent park.
For under 6s they have some really cute kiddy rides and play areas.
For preteens there are a couple of smaller coasters and fair ground style rides
For thrill seeker (teens and usually dads

) some brilliant roller coasters
For adults some decent shows and free beer
For the whole family there are some excellent log flume rides ( put Disney's efforts at AK to shame) , good animal enclosures, feeding paraketes and overall I thought the food was pretty good as well.
Cindy, maybe you had an unfortunate day, but to complain about a 20 minute wait time for a major ride I think is unfair ( and I judge the rest of your comments from that) . On trips to Disney's parks I'd be overjoyed if the average wait for the better rides was 20 minutes let alone the worst.
I agree BG can be a lot of walking and is pretty hot. Drink lots (not just beer LOL) , use sun screen and beware of the water rides, you will get VERY wet. In the summer this can be very refreshing, but pick clothes that dry of reasonably quickly as you don't want to be walking about in sodden jeans all afternoon. I would also take a change of clothes, even if just for the car journey home.
