just need two nights as we are taking a break from camping and staying at a hotel. who knows the answer to this?

We’ll be on vacation next week, and have a night reserved camping in Zion on Friday, and reservations at the Mirage in Las Vegas on Sunday. However, we have a gap on Saturday, and I was wondering if there’s any place interesting to spend the night to break up the journey from Zion to Vegas? Do St. George, Hurricane or Springdale have much to offer? Or even something more along the way to Vegas? I think at this point we’re probably not too interested in camping, so staying in a hotel at some town would be nice. Thanks!
