Lodging and timing in Sedona

Hello following up on my inquiry posted on 4/10. Just looking for advice on switching our visit to Sedona from the beginning to the end of our trip if that means we would be there over Columbus Day weekend? Too crowded? Will be in Grand Canyon 2 nights, then a free night, Bryce for one and Zion for two. Looking to spend 2 or 3 nights in Sedona.

And do you recommend Casa Sedona Inn? Is that a good location? Thanks very much
