As a matter of full disclosure I have to say that I use Marriott more than other brands as I have a family member who works for them and I sometimes get Friends and Family rates.
We were staying just for two nights on a flying visit from the UK for a wedding. The staff were very friendly and helpfull and the room was very comfortable, these are what I now expect from a Marriott.
Car Parking is charged and I am not sure they need to do that, It would be better with a pool but that is being picky, my only gripe was returning on a Saturday and not being able to get something to eat at 2pm. We had to schelp to a local fast food restaurant only to find upon our return that they had served some peopel after we had left!
