SO SO, too expensive for what you get
I stay at this hotel often for business so it is not that big of a deal to me as I do not spend much time there. However as a frequent traveler it is nothing great. It is just so so. It does have an AWESOME location so that is great, but so does the Marriott right up the road and that is a much nicer hotel with better perks.
The Westin has 2 towers, the landmark side, Haunted, Old, super scary, dirty, don't ever stay there, if I had to rank that side it would be POOR at best. The other side is the Tower side which is newer and what you would expect from a Westin. It is much nicer and cleaner, still nothing great, but nicer rooms.
Everything is super expensive, breakfast will run you 30$ if you do the buffet, if you want a snack at the breakfast bar, coffee and a sandwich will be over $10. To use the Gym if you are not platinum you have to pay $10/night, ridiculous. The Marriott gym is Free to all and they also offer a free lounge with breakfast, night snacks and desserts if you are a Gold Member.
Service is fine at the hotel, have not had many experiences, 1 that was unpleasant but that was it after more than 10 stays. So all in all, it is a great location, super expensive, and just so so, but do not stay in the Landmark side, unless you like the movie Shining!!!!
