We stayed at the casino one year with good luck ( no pun). But I could see it being a problem with even marginal snow. The trail north used plowed roads, and was stop and go. We lucked out and the lake was frozen solid, so we were able to ride it from the Green Light tavern and saved some time and hassle of finding roads to lead us west.
On the way back down we took the long loop around. Fun ride, but it was late and took quite a bit longer.
-I think that casino room was like $45 and then they gave us two $10 rolls of quarters to use.
