Personally Marty after sleeping 80k's offshore enough time there is nothing I require. I'll be doing the boat sleep (coz I'm too friggin lazy to bring camping gear), food and drinkies I can go with whatever and as for a loo..........well, I've got a decent anchor well.
Whatever you decide I'm sure it'll be a great get together, let's face it.............when has a M&G ever been about the location?
