I just stayed there this week and got a Star Class upgrade due to Bonvoy status. Since the hotel was not anywhere near capacity I really did not see much of a value in having Star Class, however, I do think that it could make a difference when visiting while the hotel is fuller. Star Class gets you access to a lounge with premium liquor brands which might pay for itself if you're a drinker, you also get access to all restaurants without reservation, a dedicated concierge (who we never met or heard from), access to a Star Class pool which is a bit quieter, among other things. Overall, we had a great time and would definitely go back.
