The Marriott Gateway and Springhill Suites Gateway are newer hotels, not in a sketchy area and share a rental car train stop. You just hop on the rental car train steps outside the airport terminal, go one exit and the hotel is there. No waiting for or crawling in a dirty van being driven by who-knows, no worries about getting caught in traffic exiting in the airport, and no sketchy neighborhood. Friends actually went back to the airport for dinner when they were staying there on a layover, eating at a Chinese ff restaurant in the atrium.
I have always thought the only thing keeping that CY from changing badges to a Baymont or America's Best were people who don't know any better.
