Mostly played the ticket/credit indoor games. Came on a Sunday afternoon and the place was pretty full - mainly kids but also some adults. Paid $30 for 200 credits to use, and game were typically 4 to 6 credits each. There are some games where one swipe is sufficient for both players, so make sure to read the labels!
For a Sunday afternoon, the lineups were reasonable. At any given point in time, there were almost always somebody at each game, but it was usually only a few minutes wait. Their games were alright, nothing too spectacular or surprising.
The redemption counter lineup on the other hand was a completely different story. Much, longer and also far slower as people took a long time to decide on their toys. You could be waiting there for half an hour or so.
