We Purchased Zoo light tickets on line, trying to be pro active. Our guests were from out of town and we really wanted to take them to see the lights. We waited in a line of over an hour trying to just get into the parking lot. As we had a small child who was getting fussy we were unable to wait any longer. I contacted the zoo about a refund, they were kind enough to offer tickets to a different day, unfortunately we have very hectic schedules and the night we tried to go was the only date we had available. I told them this....STILL waiting for a response. So buyer beware, Don't buy your tickets until you make it to the gate!
