Just to be clear about Wendover, NV. There are a few motels on the Wendover, UT side, the best being the Best Western, formerly, the Days Inn.
However, there are no casino hotels that cross the border. Atleast not today, can’t vouch for decades before.
The closest casino in West Wendover to Utah is Montego Bay. They are actually located ON the state line. Their clientele is mostly Utah, but get some California business as well. There are several other casinos in West Wendover, but a number of them are jointly owned. They observe Mountain Time, a rarity in Nevada, as most of their business is from Utah.
