We stayed in March at Black Barts campground right off of I40 in Flagstaff. Kind of a dumpy little campground, but cheap, quiet and very convenient to almost everything. There is a good steakhouse on the premises with singing waiters that's good for a fun evening. Also close by are the cliff dwellings at Walnut Canyon. Allow several hours as there is a good climb to see them, but it's very interesting and worth the stop.
