I purchased 2 tickets for the elephant encounter and we had an emergency come up so we were not able to make the encounter. I emailed them and they won t even try to work with us on trying to get on for another day. Instead they just said they are non refundable! For something that is so expensive you would think they would be a little more understanding now I just wasted over $440 on something I can t do! I definitely will never be going back to this zoo! DO BETTER HOUSTON ZOO!
