How long does it take to go through all of the wonders of wildlife and is there plenty of bathrooms in the new area?

We "buzzed" through both parts in right at 2 hours. But no children with us, and we did not look at all the trophies or through the "halls of fame". I have no info on bathroom facilities.

2 to 3 hrs if you dont care looking at fishing poles, boats, and pics of famous fishermen ☺. We went with 4 small kids, it was a great experience.

It took us about 6 hours with about an hour between the two for a lunch break included in the 6 hours.

Up to a few hours, facilities always close by.
