I bounce back and forth between the Sheraton and Springhill Suites.
The Sheraton posted price may be a little high (usually $78 out the door) and the Springhill is around $84.
Both have reliable van service but the Sheraton is every 20 minutes while Springhill is at the top and bottom of the hour.
I actually prefer the Sheraton since it is closer to Leonardo's.
