I think you would like either motel. I have stayed at both, although the Camelot was a few years ago. I liked them both. Both about the same walk distance. The Camelot may be a few more steps, but nothing that would make a difference. The Camelot has no breakfast, the Desert Inn has a continental breakfast that is very limited. That may make a difference to you, didn't to us as there really was nothing at the Desert Inn that we liked at the breakfast anyway. We bring bars to eat in the room. I tried to book the Desert Inn again for my trip in Oct, but the price was prohibitive, so we are staying at the Del Sol Inn.
I would go with the 2 bathrooms if they are about the same price. While not a necessity, it's nice for 4 adults. Even if 2 of you shower at night, you still have 2 bathrooms for other uses. haha!
