We will be in San Diego next week and I am trying to finalize our trip details. We set aside Sunday and Monday for Sea World and the Zoo. We also have Padres tickets for Monday night. My question is which place will probably take us longer to go through. It's myself, my hubby and 2 kids (9 and 7). My kids are more into thrill rides than animals. So I'm thinking Sea World on Sunday plus the Zoo opens earlier so we should do that on game day? Also, should we buy the express bus pass at the zoo and is the Ice Age 4D show worth seeing? Any suggestions are appreciated.
