I'm personally fond of Southern Utah's parks and scenery. Plenty of golf too. A few Hilton properties on the way to Las Vegas. St. George, in particular, is in a nice area. Not big on the tourist glitz, though. And the hotels are on the "basic" end: Hamptons and HGIs. So, if this trip is to have anything of an indulgent or hedonistic bent, probably not.
Spokane has a good Doubletree, and the city is nice-enough, if inelegant. Good riverfront and parks. But nothing to compare to Seattle or Denver. Dining options tend toward the folksy, rather than elegant or gourmet.
