Hi all, my fiance and I are planning our trip for late May of 2010. One of the things we are trying to do this year is break the trip up, unlike last year going from East Coast to Hawaii all in one shot. We are planning on going back to Hawaii, but we would like to stop in Arizona for a long weekend if possible. We anticipate leaving Saturday the 15th bright and early, landing in Phoenix around 10AM. We'd like to see Grand Canyon and the natural beauty of Sedona. Supposing we only had a "long weekend" to stay, what is a realistic number of days we should budget for a few of the must-sees? For instance, what would be a travesty if we missed?
