Hello Tom,
There are a few places in Mesquite and they are all nice. Some nicer than others, Just depending on the budget. The Casa Blanca is nice and also the Oasis which is just across the street. These 2 will be a little more expensive. Then there is the Virgin River which is owned by the same people that has the Casa Blanca and Oasis. Its cheaper but still clean. Then there is the Eureka and its nice too. The ones I like are either the Casa Blanca or Oasis. I have stayed at them all and have had a nice stay at all of them. But prefer the Casa Blanca or Oasis. I guess it really is a matter of what you like. Feel free to contact me direct with any questions. I work with all the properties and can help with any questions you may have. Take care and have a great trip. I live in Utah and have to Boast of our beautiful parks in Zion and Bryce. You will love it.
