We've done this several ways and it depended on the boat we were on.
For the no TP toilets we had sandwich size zip top bags for poo and those were sealed and put in waste bin lined with trash bag. TP used for pee only was just put in trash bin. Throw out trash bag as needed.
On another boat where we could flush TP we "threatened" our crew if they got the toilet clogged they were responsible for full payment to get it unclogged. They should use as little paper as possible. Well, at the end of the trip (of 10 days) I realized a 4 pack for one of the cabins had 3 rolls left from the 2 people. I asked why so much left and we had scared them so bad they were afraid to use much at all. Used about 1 square per usage. 😂😂😂 We really didn't mean THAT little but kudos to them. Now we have great stories for life!
Use bathrooms on shore as much as possible also helps.
Check out Guavaberry Spring Bay. They are getting back together and can help you find what you need. The sargassum is not on the Sir Francis Drake Channel side on Virgin Gorda, but is on a few places on the Atlantic side, which you won't go to anyway. Spring Bay is our go to place. It is a short walk from the Baths and connects to other beaches such as Little Trunk and Valley Trunk. We were down for three weeks in May and had no mosquitos and a nice breeze. Enjoy!
Does anyone know if Euphoria, on Virgin Gorda is being rebuilt? I have spent many happy vacationing weeks there. Haven't seen Mike on here lately. It was a beautiful villa with spectacular views. Thanks
The coffee shop in Soper's is " Omar's ( De Best Cup) and I would highly recommend it for breakfast or early lunch ( they serve food til 12.30).Bottomless Mimosas and Bloody Mary's too..with WiFi. Omar's was a God saver for those of us down soon after Irma and they ( he) deserve to thrive.
