Heading up in a few hours myself.
There are lots of good restaurants and yes, there's a casino. Le Diable has good micro brew if that interests you.
Haven't seen the parks this year since it was early season when I was last there. Generally, they're pretty good and there's a few of them. I'm not a park guy so I really don't know what I'm talking about.There's a half pipe and a jump line and some bigger rails and boxes up top, smaller stuff in the other parks.
The south side fronts the main village and has the gondola. Gets pretty busy. The North side has a bunch of good runs and is generally less crowded. The Soleil side has long, meandering rollers and glades, The Edge has a slow old double, but nice glades.
Generally, we avoid coming down to the south side base until late in the day....the lines are nuts. Hit the Edge or North Side early until the lines get long, then go lap the Soleil or do top to bottoms on the North Side.
See what's up with the ice and what is good/bad and take it from there.
