You don't say where in Tahoe -- it is sharply divided between North Shore and South Shore. North Shore is a lot nicer but is mostly residential (few hotels). Hyatt is pretty much the closest to a luxury hotel at Tahoe that is publicly available. South shore is where all the casinos are. Personally I prefer skiing at Alpine Meadows and stay at Granlibakken which has some interesting character and scenery http://www.granlibakken.com/
