I am planning a trip the last week of July to San Diego and then LA. I will be flying into San Diego around 11am on a Tuesday, and leaving for LA on Friday morning. I am planning one night at the Mission Bay Hyatt and wanting to check out Sea World, Mission Bay Beach and the Seaside Cliffs. Originally I was going to do two nights in Mission Bay and one at the Andaz San Diego. But I'm wanting to go to the San Diego Zoo and Coronado Beach so I am thinking I would need two days in downtown San Diego. Does this sound like a good plan? Or should I throw one of those nights to the Grand Hyatt? I don't need to be at the beach all day, maybe just a few hours. I won't have a car, so will be doing public transportation and uber.

Thanks!
