Just completed the escape room on Oasis this week (and with over 7 minutes to spare, the staff member told us it was the fastest he had personally seen).
My wife and I do a lot of escape rooms, we are snobs, and both of us thought it was incredibly well built (and actually quite challenging).
Oasis also had a Museum Heist Puzzle Competition (made by the same people who do the escape rooms). It was really cool, except that one of the clues, which is vital to completing the puzzle, was missing from a bunch of the group bags. When we asked the staff they said they were aware of the problem and waiting for replacements. Really wish they would let people know a piece was missing and at least have a picture of it available to look at.
