I usually stay at the Courtyard Marriott whenever I travel to Chandler. I think the hotel is fairly new and service is always friendly.
It's weird that they have the slightly lower end Fairfield Inn & Suites Marriott right next door (the buildings connect). I think the staff is shared across both hotels....although, it should really just be the same hotel.
They offer free internet (WiFi or LAN cable)....they have a full bar in the lobby (but it closes at 10 pm). They offer a free breakfast but you have to walk over to the connecting Fairfield Inn & Suites to get it.
I've stayed at both the Courtyard Marriott and the Fairfield Inn & Suites at this location. The Courtyard was about $10 more expensive per night....and the room had a couch in it where the Fairfield Inn & Suites did not.
