If your buddy can get you, et al , OUT there, you could buy a one-way ticket and RETURN on the sightseeing boat. We've come back on that
a couple of times. It takes a little time to help educate the ticket 'master' at Wahweap that you can, in fact, buy 1/2 a ticket. The full
ticket is currently $100 + fees.
If you get 'critical mass', maybe a charter would be economically feasible. I think that they run an 'executive services' office @ Wahweap - we used them once too - they came in a v- hull party barge to fetch us @ R.B.. They forgot to bring us our our beer so we diverted to D.R. on the way back to Wahweap. Had to choke down Bud, but I lived through it.
