My wife and I stayed here 12/29-1/1 and everything was just fine. Yes, the hotel is a little older but it is not a dump. I would not be comfortable paying a premium for their Conference room suites or any of the others, but I would not have a problem staying there in the future. It was explained to me that San Diego is somewhat unique in that Hyatt does not own any of the 3 properties in the area. The owners of Islandia (with a threat from Hyatt) are undertaking a massive renovation this summer.
This would not be my first choice, especially for business, but it's O.K.
