You definitely wouldn't be disappointed with the trip. If you haven't gone to Sedona previously, it is pretty remarkable. The red rocks are just stunning! I'm sure that you'll get a group going up there. We would have actually gone to Sedona for the drive, however the logistics of getting through Sedona are just too difficult.
Do keep in mind that we highly recommend going directly to Pinncale Peak afterwards, as there would most likely not be enough time to get to the hotel, and then back up to Pinnacle Peak. So plan accordingly for change of clothes, etc. This is pretty convenient as far as driving goes since Pinnacle Peak is pretty much on the way back down from Sedona.
Have fun if you get a group going! :smile:
