Is this what you were asking?
I doubt it, but here goes anyway.

The timeshare that might add the most to your trip/vacation experience is The Kimbal in SLC. It is right at Temple Square, close to most convention sites as well as downtown and the symphony. There are quite a number of sights to see in or near Salt Lake City, so extending your stay to a comfortable week might be a better experience than driving hours and hours trying to do what might turn out to be too much.
My second recommendation would be St. George, to include Zion, Bryce, and several other specacular locations in Southern Utah. Very workable alternatives would include Mesquite and Brian Head. If you want to throw some money around, Vegas is an easy drive from any of these for a day trip.
We have enjoyed laid back vacations and we have enjoyed "go every moment" vacations. Consider all your options before you decide.
BTW, we are out the door soon, for Vegas, for what is supposed to be a laid back trip. It will be interesting, going to Vegas just for the sights for the first time in about seven or eight trips. First time in a timeshare there, too. I always thought a timeshare in Vegas was silly. You could get all those cheap hotel rooms, especially downtown, which we preferred. Things have changed, and it will be interesting to walk on the other side. What does
that have to do with anything? It's just what I suggested you consider, a little different kind of vacation.
