We threw a birthday party at the zoo and was told a certain pricing. After the party was over we were informed that too many people came and they charged us an extra $130.00!! I find this very infuriating considering they didnt even collect the passes they gave us to turn in when we arrived. We also would have asked parents to drop off their kids and not stay if this was going to be an issue but instead of informing us right away they waited until after the party. I would not recommend having a birthday party for your child here considering we paid $250.00 just for a room and to see two animals for maybe 15 minutes. Very displeased with the whole experience.
