Nice to see you post Robert! Sounds like an awesome trip.

The blow up float is a great idea. Alice and I took them when we were on the PG to use the couple of times we went to a beach. We found that because of the current, we tended to float away from our spot on the beach. So we used the nylon clothes line we always bring on trips to supplement the clothes lines in the ship bathroom. We got a lead weight from the ship's dive gear that is designed to go through a belt, so there was a way to tie the clothes line on it. That way we just tossed it in the water and were able to float in place and not have to paddle back up into the current or get out of the water and walk back up on the beach. If you are not going to be on a beach, but instead will spend time in the water off your bungalow, you could just tie up to a piling or the deck somehow.

I think just get a drink at the bar at Bloody Mary's is a good call.
