Challenge Nation Jenga Clue
You're already on the internet, so this shouldn't be too hard: TripAdvisor.com lists a whopping 343 “things to do” in Orlando—find the location of any one of them in the top THIRTY, as long as it's an actual building/structure, not a "feature" or similar AND does not overlap with any other clue's goal!
Once at the most recognizable spot at your chosen location, gather up at least four strangers (or another Challenge team) and spell out O-R-L with your combined bodies out front!
