Hi Melissa, how many people would the party be for? I’m dying to plan an escape room event but my clients either have too many people or too few Anyway, these guys seem to do a mobile version that comes to you https://goo.gl/SsyJLC
Some other ideas:
Cheese tasting? Rum tasting?
Pub sports tournament - table tennis/darts/skittles?
What about perfume/aftershave class?
Or you could put everyone into teams and reenact some kind of nostalgic TV game show, e.g. Krypton Factor, Family Fortunes, Mastermind, Question of Sport etc etc?
