OK but not as described on website or in brochure
We sayed at the Hyatt Mission Bay in San Diego for 2 nights in August 2012 during a tour around California. Our holiday was booked through Virgin who provided a generally excellent service sorting out our itinery. Their brochure describes this hotel as having "undergone a remarkable transformation" being "bigger and better than before" and having 3 swimming pools and a "fantastic water playground". Sadly there was no evidence to our eyes of any recent refurbishment to our room, which was comfortable but not spectacular and the only fantastic thing about the water playground and 3 swimming pools was that they were invisible! There was one unremarkable swimming pool and it was so crowded when we arrived in the afternoon that there were no sun loungers available and other a guests were using the adjacent cafe chairs instead. We checked Hyatt's own website and found its description identical to the Virgin brochure. 
I would suggest anybody booking this hotel on the basis of the current website and brochure descriptions thinks again.
