We were in Colter Bay two years ago on one of our three trips there each summer and used one of the ADA sites when our son and his family joined us for three days. They reserve them for most of the day but will lets people without disabilities use them when they don't fill up around 2:00 or 3:00. Our daughter-in-law has a C-Pap machine so the electric was good to have but there is some type of designation you need to get to just get into the site early, don't know what it is but some kind of disabled pass I think. As far as the site is concerned, they are quite roomy with electric only and are very level for the most part. Not all are paved, but even the dirt/gravel ones are very nice.
How long does it take to re-charge the wheelchair? If you can't get into one of the ADA sites, you can run a generator from 8:00 am to 8:00 pm in about half the sites so, after sightseeing, you might have three or four hours to recharge before having to shut the generator off, if you have one.
