Stayed here one night to stay close to the Airport, so I can't get into exactly too much experience to go off of.
First off, the hotel is located close to the airport, but the airport is a bit of a drive from everything else. So if you plan to have dinner outside of the hotel, be prepare to leave early, especially if you're leaving around rush hour.
The Valet Car Service is absolutely horrible. Every single time I needed them to bring my car over, was just a frustrating experience. Each time I would call about 10 mins before heading downstairs, and each time I waited for over 15 mins for me to get my car. It was never ready, and half the time, they forgot I even called from my room. So, I guess call ahead before you go downstairs, and make sure you make it clear you want it ready when you get down. Otherwise, they'll just forget.
As far as everything else, the room itself had newer amenities, (flat screen television, hook ups for your laptop, etc) I believe it's one of those new "modern" Marriotts that they're now advertising. Also they've got more than one restaurant on site, so if you're planning a bite to eat, with no hassle, that seems to be a plus.
If only the Valet didn't suck so hard, I would feel more inclined to give this place a thumbs up.
