Hint Hunt London: Submarine Deepdown

Hint Hunt run two different games out of the submarine room.  We found this room quite frustrating because of this.  Red herrings and diversions are one thing, and part of the puzzle experience, but things that were genuinely puzzle parts but for a completely different game arc became annoying.  There is a part of the game which requires physical dexterity in a confined space which really should have been designed to be larger - only one member of our group of 6 was physically able to do this due to space constraints.
