Chiquita discovered that if you don't want to get dumped in the ocean every time you ride the Zepplin, just go part way down the stairs in the middle of the craft.  You'll be able to stay on for the entire ride then!
Thanks Chiquita!

Oddly I find I never get dumped from the Zepplin.. my only problem is occasionally it NEVER comes along.. but rest assured every time it does and I ride it, I get the full tour from station to station... in previous versions I got dumped by the boats sometimes, but that was BEFORE Burning Crusade...
