What they said above, pretty much. Our tour didn't get the bottled water, but we went in March. The gave everyone an ear piece to wear to make it easier to hear the guide.
We rode JC and HM. POC was closed at the time, so we didn't get to ride it.
We had lunch at Columbia Harbor House. It was good, not spectacular.
I have to say the tour is probably one of the best values at WDW though, especially once you factor in the price of lunch.
We really enjoyed ourselves and are glad we did it.
