After a workshop with Michael last December south of Albequerue, I took 5 days and headed north.
Canyon de Chelley - 1.5 days
Monument Valley - 1 day (overnight)
Antelope Canyon - (lower) 1 day
I am headed out to Utah in a month for 2 weeks and since I ended up being "unsatisfied" with the blow through approach, I am cutting back on locations.
Good luck if you stick to your plan, You will certainlly end up wanting to come back for more.
