I stayed here last year complimentary based on play from previous trips. The room was nice and a pretty high floor with a good city view. No tip required.
Just returned from my last trip where I had to tip to get an upgrade (and was well worth it - poolside 3rd floor to city view 37th). However the room was for my bachelor party and was unable to get a bigger room even after tipping and paying for the most expensive night. Luckily there was only 4 of us and we managed to make it work - thank goodness for 2 sinks in the bathroom!
I will say it is the little things that caused me to only give 3 stars. No corkscrew opener for the wine, no ethernet cable provided for wired internet (although the wifi signal was actually strong enough unlike most hotels), the iron kept leaking and to take care of all this involved a front desk trip cuz all 3 of our room phones didnt work! We weren't even offered a change of room and they never fixed the problem. They sure missed out on a ton of room service!
The casino was pretty good except the only doubledeck blackjack tables were $50 minimum at all times where most others are only $25 for doubledeck. Best place to eat is cafe vetro before 11 pm to take advantage of the full menu (french dip hint hint)
I would stay here again but only if I was given an offer. I would not request this place after be treated so poorly as a Platinum Mlife member!
