We went in 2004. Wife & I along with Brother in law & Sister in Law. I had one hummingbird land on my finger and feed and it was a great experience. I spent most of the rest of the time trying to take pictures. The caretaker put some small seeds that looked like thistle seeds on Bet and her Sisters legs and they had some finch like birds land and eat seeds off their legs. We combined it with a raft ride down the great river from the Lethe Estate. I say do it but pick a day that there is no cruise ship in port. We were the only ones there for the first hour and it was great.
