We went in October last year. It was a pleasant afternoon out, and quite a relaxing day out for everyone. It's not huge but It was good fun to see the gators, and there were a couple of shows on which the kids enjoyed - one of them involved a man wrestling a Gator.
My son got his photo taken holding a tiny gator and also with a snake round his shoulders! A good souveineer to take home and show his pals.
I dont know how much it would cost to get there, but MouseSavers.com has a Taxi service price calculator that can give you an idea how much it costs to get from A to B .
Hope this helps,
Lisa
