I happen to know the resort in question (I helped with some of the network design, remotely).
The generator is not your run of the mill small generator, it's built to run the entire resort, and the power quality should be decent.

I am a friend of Harry's (the one who roped him into helping with the network). I have been going to PSR for over a decade, and am very familiar with their operation. I have no financial interest in PSR, but am friends with the owners, and my son works there as restaurant manager (among other things).
PSR is indeed off-grid, and generates all their electricity via diesel generator. The main unit is a new 135 KW generator. The generator has significant safeguards for voltage and frequency variations. However, as folks have pointed out, PSR can make no guarantees of the suitability for the power for charging cars. The campground hookups are at the far end of the line, furthest from the generator. As such, at times, the voltage may be a bit low on that side of the road. PSR has received comments that some very new RVs will not allow connection to the power.
The campground does indeed have 9 Full hookup RV sites that have 120V 50amp power available. There is no charging available at the motel rooms. You may be able to call them , and discuss your options. Telling them I mentioned this may help.
With electric vehicles being a fairly new occurrence, combined with the remoteness of PSR, I would not expect this to change anytime soon (lack of specific charging stations). It is, however, something I will bring up to management the next time I'm out there.
And yes, solar would be great. It is being looked at for use fro certain applications at the resort. But lack of a grid to tie into makes the cost factors substantially different.
If you have other questions about PSR, I'd be happy to try and answer them. They do have a tremendous beer selection!
