The only one I have stayed at is Wynn and I love it there and don't think I am old at heart?? HHH
Cosmo rooms with the balcony are nice for the view. Have been in their rooms a few times. Don't love their casino.
Like the fact that Aria is fine with people taking pictures of slot wins! I have only visited it once to eat there.
