I was really looking forward to Cottonwood camp, outside of the Sedona area.  The campground had excellent reviews so we booked three nights.  There are many different sections of the park and your experience overall could be impacted by which site.  We were in site 141 close to the main activity room.  These sites are very packed and there are a lot of long-term guests and it looks like it.  The other sites throughout the park are better, especially the ones on the ridge with a view.  

The other challenge was almost zero connectivity even using a hot spot.  I work remote so this was a challenge and I had to take work calls in the public lodge.  The lack of WiFi at all limited our other devices as well.  Not an option if you work on the road.

The area however has amazing natural beauty, parks and lots of hikes.  Some are dog-friendly, but some are not, so recommend checking.  The town of Sedona has changed over the years with many more tourists, traffic and high prices.  I would likely not return or stay somewhere more in nature, but with cell service as well.
