I done it on my own last year for a long weekend... I went to Les Houches near Chamonix, stayed in a little hotel called La Barme ..... £39 a night in a single room, could had fitted a double bed at a squeeze but the location was great for the gondola... it was a bit of a walk into town but that wasn't an issue after a jar or five.
Many places offer single occupancy, hotels.com or bookings.com are great places to find these... well that is where I look.
