The name of the game at this place is making sure you create more demand than you can supply. I called before purchasing a Groupon to get the details. It all sounded good. I told her we would be there on a Friday. Did we need a reservation? No. Were there any special exclusions for the Groupon? Nope.
So we walk in to ride at 11am and we're told there is at least a 3 hr wait and they have a reservation for a large party at 4pm so it will be at least 7pm before we get on and she couldn't guarantee that. We asked about different days, other times... nada. There were at least 3 other out of town groups that came in while we were there and they were all in the same boat. Some of them opted to wait. That's no way to spend your vacation time.
With so many people coming in from out of town it's just not right to create a promotion you can't honor. The business' recommendation? Get a refund from Groupon. So their lack of capacity now becomes a problem for me and the promoter they hired. Just not well run.
