I stopped briefly in the Dells on my way to Milwaukee last week and have to return back that way this week.

There's an 'arcade' of sorts on Broadway that has an OK Terminator 3 game. It was the only game I came across on my brief stop.

Here's a somewhat recent thread on Pinball in the Dells:

The Pinmap doesn't list 'Wilderness' as having any pins, but you could call them and ask?

It definitely looks like they have an arcade, but I can't see any pinball games.

I remember going to the Dells as a kid, but we always stayed in one of those older hotels near Broadway and spent the days visiting the public beaches and browsing the fudge shops, wax/horror museums and a place that let you record your own music videos.

I've stayed at the wilderness a few times over the last few years. Sadly, they have no pins in their arcades on the property. Check the basement of the Moose Jaw resturant. They have a small arcade and usually have a few newer Sterns

Just got back from Great Wolf Lodge over the weekend, unfortuneately, no pins there. Chuckleheads arcade is just across the street from it, none there either.

Bummer. I'm going to the Dells on vacation also. Hope someone can tell us about some pins there. How about Great America? I'm hitting all the tourist traps!

There's a really nice Avengers Pro and XMen Pro at Moosejaw Pizza in the Dells. There's also typically a POTC at Pirates Cove Adventure golf.

Mount Olympus has avengers pro, xmen pro and ac/dc pro.
