We plan to visit Arizona in late April. We will likely be staying in Sedona, but plan to do one overnight stay in GCNP. We have some flexibility on when to go to the park. I'm not sure if any particular days of the week tend to be more or less crowded than others.
I'm currently leaning toward either the Wed or Thu night of our week-long trip.Edited: 03 November 2010, 19:56
