In the world of escape rooms newer is better. This is the older of the two Exit Strategy locations and it certainly shows.
Location: poorly lit industrial and or commercial park. Strip of nondescript buildings near truck rental and other distribution industry lots. No nearby restaurants or anything for the public. They must be getting a great deal on a lease because there is no other reason to choose this location unless you want zero foot traffic.
The room: I did lost in space, all I can say is don't. The challenges were either obvious or obtuse. There was no thematic or story reason to find certain clues needed to complete tasks other than the clue was there and you hadn't used it yet. I don't want to spoil it for you and I won't. It was almost entirely fetch the key find the combination.
Number of participants: they say eight max, but unless you want to volunteer to be one of the four people doing nothing then I suggest four max. In my opinion the optimal number would be three people, or two if very experienced.
The operator assured me the other rooms were newer and better. I would have gladly accepted this advice prior to paying for the room, it didn't do me any good afterwards.
Go to the North Location and do the Ruins, it sets a high standard with not so obvious fetch clues.
