I typically stay at Hilton and honestly never tried a Spring hill Suites until my last two night stay for business.
Very clean room, excellent staff, and close to restaurants and entertainment. Parking was free and ample. There is no restaurant on site and breakfast is continental and left room for improvement in the hot items. Fitness center has three pieces of cardio equipment, so better off running outside when the weather is right. Ample sidewalks along the road the hotel sits on and light hills.
Overall a nice hotel and would stay again.
