I can reccomend 2 rivers, both well known. Lees Ferry (there is a campground very close to the Walk-in Area but it's nothing to write home about...all rocks and gravel) and the San Juan (there's a fine campground there with good sanitary facilities, etc.).

Both rivers have reasonable motels in the close neighborhood. Drop me an email and I'll give you the name of two very very good guides.
