I did Zion and Bryce on the same day, leaving for Zion from St. George and spending about four hours there, then driving to Bryce and only spending about two hours there before driving to Provo. I found myself wishing I could have spent more time at Bryce, but that's all I had time for. I saw some decent Best Westerns around Bryce so could have given myself a few extra hours there had I decided to camp there for the night instead of pressing on to Provo.
