Pay attention when booking, but no regrets
Except Birch Aquarium where we had to go to the ticket office first then we could redeem our passes, CityPass in San Diego was really a great option for us since we were heading to as many places CityPass had tickets for. This made traveling easier only one person needed to have the tickets for everyone. We all were able to get into our locations and enjoy the experiences. I would say keep an eye when booking, I thought I had gotten a SeaWorld + 2 locations, turns out I had booked SeaWorld, Zoo/Safari Park, +3 more locations. I regret not using the last pass before we had to leave. Overall, I would use CityPass again in a place like San Diego where there are multiple close venues that would warrant a full day trip for each.
