OK, everyone! I took all your comments to heart and went back and checked the online campsites. Guess what- some had opened up! So I talked with a very nice and helpful ranger (miracle!) and here is our revised schedule for next week:
Monday: Drive from Durango, last minute gas, beer, wine (you know- the essentials) in Moab and then check in at the Island in the Sky visitor center (4-5 hours) Then drive (slowly) down Shafer Trail and camp at Shafer campsite.
Tuesday: Take our time, visit Musselman Arch and maybe Lathrop Canyon. Camp at Airport
Wednesday: Detour to White Crack and then camp at Murphy.
Thursday: Fort Ruin hike and maybe Upheaval, camp at Labryinth.
Friday: Maybe sneak up Taylor Road for a look-see, then drive out Mineral Road and head for Durango.
We thought this would be a more balanced itinerary. What say you folks?
