Certainly passengers take day trips while cruise ships are in for the day or night. Taking personal responsibility outside of the ships sponsored partners to get more than 20 fellow passengers on boats to the outer islands and back before the ship departs is something I would try to avoid taking any responsibility for. If your group of 20 plus misses the ship departure then what? Not to mention trying to play treasurer for the group. No all people pay what they promise when they promise.

If you would be delighted to fund the entire side adventure and any surprises out of your own purse. Then please leap right into these plans.
