Was reading on the Royal Caribbean web-site where they are putting in these rock climbing "walls" on older ships, so if you aren't on any of the Voyager or Radiance class you can still go for the climb :-)
I actually did it on Radiance a few weeks ago and it was thrilling, scary too, but I think I'd actually do it again. May-be on Voyager next Feb :-)
I might just harness myself up and let the wall attendant hoist me as I sing:
"What can you do with a drunken tourist?...Haul away! And up he rises" <> :-)
I may dwell on the land, but I live at sea!
Sensation 2/03 I disembarked, but never really left the ship.
Sensation 04/05 The vessel made me do it!
