Exactly! I complained about the slow-moving entry process when I was at Frankfurt Zoo this summer. The zoo is brutal for getting people swiftly through the door, then of course the Grzimek House doesn't open for another 30 minutes and the Exotarium doesn't open for another hour. There should be self-directed kiosks, pre-sold tickets and a desire to keep people from impatiently waiting in line. During my visit I saw families with little kids spend ages shuffling forward in line while a couple of senior citizens handed out tickets at the speed of sloths. Also, the whole zoo should open at the allotted time instead of in sections. No wonder some of the TripAdvisor reports are negative, although in truth I gave the zoo a glowing review. There are some simple items that can easily be fixed to make Franfurt Zoo even better.
