That's a tough time for a one night stay, as most places will have minimums. Also, what's your price range? Silver Queen is on lower Main street right next to Town Lift--probably run you 200-250 for the night. That's probably your best mid-range, walk to everything bet.
Copperbottom Inn is not exactly "right next to" anything, but is right on shuttle route and has a great restaurant attached to it. Room will be a step down from Silver Queen.
Chateau Apres is livin' on the cheap. But, it can be a really fun place if you let it be. Has a great fireplace, and a fairly decent location about 500 yards from base. Also, they definitely don't have a minimum (last time I stayed, they wouldn't even let me give them a credit card number, they just took my name and said that was all they needed to book the room).
Another option is Treasure Mountain Inn, but again, I think you might run into minimum night problems. It is a condo-hotel, so all of the rooms are privately owned, though managed centrally. Again, you can either walk the 5 blocks to the lift, walk up the ski stairs right next to you to the catwalk and ski to the lift, or take the trolley that comes every 3-5 minutes to the lift (I am talking Town Lift).
Not a lot of straight up "hotel" options in PC like in other ski towns, but the whole damn town is basically for rent, so you'll find something.
