Not Great but pretty good
We stayed at the Catamaran Resort and Spa 8-7 thru 8-9 while in San Diego for a wedding. We wanted to visit Sea World for a couple of days before the festivities began. I was traveling with my wife and seven year old granddaughter.
Upon check in I thought the place was a little dated. 
Room was just ok. It was dated but clean. The air condition worked well but dripped a steady stream of condensation from the vent in the ceiling. I put a trash can under it. I contacted the front desk but it did not get repaired until the next day. Hung out at the pool for a while which was full of kids. This was no big deal because granddaughter made a friend and Papa was able to have a beer and relax…until….some kid pooped in the pool and it had to be shut down. This is no fault of the hotel, the staff did a good job getting all kids out and pool area roped off with caution tape. This was a bummer but funny in that it was somewhat like a scene from Caddy Shack. 
This place grew on me with a little time. The grounds were beautiful especially at sunset. You could watch the fireworks from Sea World at night. Breakfast at the restaurant was great and the staff friendly. It seems like the longer we were there the more we liked the Catamaran. We would stay again.
