Situated right next to the SD Convention Center so very convenient for conference goers. It is your good old business hotel with everything running efficient though really nothing special about. Swimming pool and ground area between the two towers are nice but guestrooms are really not that big despite of being comfortably decorated. Bathroom is functional but also on the tight side. The good thing is every room seems to have a private balcony which opens up to a fantastic million-dollar harbor view!
Unfortunately due to heavy use during the convention week, the Club level was closed while I was there so can't comment about the service, otherwise hotel staff is friendly and very professional.
Hotel rate at Marriott during ANY convention period will likely be high but location wise, you simply can't beat it. In sum, it is a good comfortable business hotel which I will not hesitate to recommend to fellow travelers regardlessly.
