Could be much better
Stayed here recently for two separate non-consecutive nights for both catching and returning from flights. There are good things and bad to consider. Overall I would likely not chose to stay here again. We chose this place for their great online rate and the proximity to the airport (5 minutes) and they offer a free airport shuttle and free airport parking (maybe ?). Upon check-in we were told that they were now charging a $10.00 a night airport parking fee ! This came as a shock as we had done our research and even spoken to one of their associates to confirm this. When we complained we were told it "was new" and they "just started" charging ! and that the information was not yet posted on their website ! What ?! We had to argue the point and then by coincidence the clerk / associate who had actually helped us with our reservation showed up and we explained the situation. When he was told of the "new fee" he replied to his own co-worker "since when ?" The first clerk was either clueless or trying to scam us. Nonetheless we did not end up paying to park there for a few nights. As for the airport shuttle, the early morning shuttle to the airport was fine, but there were problems on the return flight pick up. Like one of the other reviewers had suggested we too waited 40 minutes for our pick up - even after calling twice ! (Its about one mile - 5 minutes in traffic). While we were waiting at the airport the other hotel shuttles came and went three times ! And when he finally arrived the van smelled of smoke. Overall the room was nice, clean and comfortable. However, we never had enough towels or wash cloths. There always seemed to be missing something. One should also note that they do post ominous warnings in the rooms about not leaving items in your car due to potential theft. The warnings were so well posted that it gave me an uneasy feeling. When I asked the desk clerk when was the most recent theft he replied "just last week." Yikes. 
And like the other reviewers stated the breakfast is disappointing for a Marriott. I expected a higher quality. They also posted that breakfast is served until 9:30 am, but one morning it closed at 9:10. Glad we had gotten their at 9:00. If you are a fan of Spring Hill because of their bars and cocktails, please note that this one does not have a bar. They have applied for their license as that was posted, but currently they do not have one. They do have a nice snack bar / sundry counter near the front desk. We found our rooms to be clean, which is most important. And I do like the two sinks and separate toilet if you are a couple and both are trying to get ready at the same time. Even though the room was clean, we found the lobby and grounds in need of cleaning, trash pick-up, vacuuming, etc. So, there was some good and some bad, but there was more bad so we will not likely stay here again.
