Just some words, hope something gives a jumpstart for an idea;
- cooking competition
- (ant)arctic exploration
- teleport repair
- Alice in Wonderland
- Murder mystery (or maybe a "missing person/animal" mystery to be more kid friendly)
- Chemics lab
- Mountain peaks
- Mongolian outbacks (inspiration of the Mongol Derby)
- Prison Escape
- Catan (not sure this would be allowed)
- Broadway Musical/Ballet/anything
- The olympics (or winter version, beach christmas was a thing too sooooo xD)
- Unknown tribe island
- Southern safari (elephants?????)
- Relaxing spa
- Shopping mall
- Sailing the 7 sea's (can be combined with the popular pirate demand)
- Cruise ship
- Mine exploration
- Classic library (getting sucked into all different kinds of old stories)
- Arabian nights
- Around the world treasure hunt (getting clues every time for the new location)
- Summer school
The more i think about cruise ship the more i feel there are a lot of posibilities around it. Deep sea diving, musical or disco night, pool area, entering a town to roam around. There can be the posh one who goes on all cruises and has seen it all and then one who got there by winning a puzzle from a paper. VIP staff tour
