Wow...I was surprised to see my old thread pop back up! Anyhow, to answer your question, no, we did not notice any increase in crowds or find that it was unmanageable anywhere we went. We flew into Phoenix on the 3rd of July and even the airport didn't seem crowded. I think the areas visited on this trip are pretty vast, so I wouldn't worry about it if I were you. We were surprised that nothing special was done on July 4th in Sedona, either by
ABD or the city of Sedona. All we received was an extra 4th of July pin from ABD.
