Alex - Frank is having difficulty accessing the site and so was unable to post a response. However, he's just posted this on the FB page - hope it helps:

"Oatman no longer has any lodging. The old Oatman Hotel lives on only as a bar/restaurant etc. (This information is via e-mail from the Chamber of Commerce at https://www.oatmangoldroad.org.) 
The nearest lodging along 66 would be either in Kingman AZ or Needles CA. Both have an assortment of motels. There is also lodging a little closer (17 miles according to the C of C) at casinos in Bullhead City AZ, but this is not on 66.
One caution: heading out of Oatman in any direction, you want to go entirely in daylight. This is a twisting, narrow mountain road. The websitehttps://www.shootingonlocation.com has sunrise/sunset times.
And fill up with gas in Kingman if you're heading west...gas in Needles CA is currently a whopping $1.50 a gallon MORE according to https://www.gasbuddy.com."

Cheers Frank - I can't account for the problems you're having as I don't know of anyone else experiencing this. I'll do some investigating.
