Brought my family to the zoo lights. The lines to get in is 2 times around the parking lot. My husband has neuropathy in the legs and cannot stand up for prolonged periods of time. Offered to show disability paperwork so he can get in before us and wait inside a cafe. Was told by 3 different employees "no" and that we must enter together. In line since 5:40 so for 40 minutes we haven't covered half of the line to go in. ADA will be notified of how accessible and accommodating the zoo is
