Indoor Viewing, Europe vs. US

[Mr. Zootycoon]

Some North American zoos are beginning to think that way as well. But to do so one needs to have a wonderful indoor experience as Burgers has. And that is very expensive to build. If one is Burgers or Randers or even Leipzig it makes sense. But would Rotterdam advertise as a great place for a cold wet day?

Rotterdam is not a great example, it does not really advertise as a good
choice when the weather is bad, but they do have quite some visable
indoor areas: lions, kudus (recently opened), Taman Indah (elephants), giraffes, gorillas...
