Looking for a place to rent for a day to get messy with a friend.
We'd love to have a huge messy session but without the hassle of the clean up.
Looking for a messy studio who could provide a custom set up for us to enjoy for a day.
Ideally in or around London but would consider travelling further for the right place.
Any availabilty for 11th / 12th / 13th November would be greatly appreciated.

I imagine that is going to be a very narrow list of venues.
A place to play, can be found especially with small numbers.
But if you want them to clean up for you too you are either looking at a specialist wam studio (maybe try Candy, messy world or DungeonMasterOne) or you are looking at paying a significant amount on top to prepare and/or clean a venue for you.
