I've seen many comments on here about games at Splitsville and comparisons to Dave and Buster's. Just so there's no confusion, they really couldn't be any more different. D&B's is more competition for DisneyQuest, not Splitsville.
Splitsville is much more of an upscale bar/lounge with bowling. I don't believe there are any arcade games there at all. Splitsville is not necessarily the place to take the kiddos for an afternoon of bowling. Sure, it will be fine for that, but it really isn't Splitsville's niche. People who are complaining about the high cost of games or shoe rentals may be missing what this place is about.
I wouldn't be surprised at all to hear about another alley being built on property for family bowling in the future. Family bowling really isn't Splitsville's target demographic.
I would imagine the focus for this location wil be for people to come in and hang out, grab drinks and get a bite. I think they're opening this location to take advantage of the limited adult offerings now available at WDW - which is brilliant. It may be that only a small portion of their customers will actually come in to bowl. The focus here may be as a bar and lounge rather than the bowling itself.
