Pam and I decided to spend our last night at the Grand Canyon Railway RV Park in Williams to avoid the heavy Labor Day traffic going back down I-17 to Phoenix. It's a nice RV park located right next to the depot for the steam train to the Grand Canyon with paved pull-thru spots (but no shade). It was sure nice to have internet, cell-phone service, electricity, running water and sewer hookups after 3 nights of roughing it dry-camping (if you can call sleeping in a 35' motorhome "roughing it", haha)!
Overall, it was a great experience. We now see what the appeal is to dry-camping that I read so much about. We'll be going back there again!
