I've tried a bunch of these in Vancouver, Seattle and Mumbai. Most of them have been incredible. If you're the kind of person who enjoys the rush of solving puzzles under a timer, you would love this.
Also, one set of rooms in Vancouver hired set designers to build the rooms (making them very realistic), and hired actors to help run the business. The actors really add to the immersive experience since they pretend to be part of the puzzle.
But yeah, I don't understand how scalable the financial model is, since the owners would have to keep recycling the rooms every few months.
Recycling is really less necessary than it would seem. There are >50 escape rooms in Warsaw. If I visit one every two weeks, I'd start running out of options only after two years. Going to escape room twice a month is pretty often anyway...
I didn't realise that one city's market could be large enough to support that many. In Vancouver I've only seen 5-6 of them, and in Mumbai where this just started, I only know of one company running them. Yes, if you have >50, recycling won't be a problem.
