I have been to Las Vegas before but never have stayed at either one of these hotels. Right now we have a Grand Tower room booked at MGM, but I can switch to PH for the same price. What is important to us is the rooms, the pool (which I know MGM is better, is it worth picking over the better location of PH though?) and also the gym. I'd love any advice!
(Oh, we're in our very early 40's if that makes a difference!)
