5. My personal musts are: Sea World (we did the Artic experience which included swimming with beluga whales which was amazing and so worth the money, book in advance if you want to do this or get to the parl early) San Diego Zoo Dinner Cruise at the Harbour which can be booked online in advanceEat in the hotel as much as possible (dinner is great too) and also a small italian covered in candles making it really romantic and very authentic italian called Little Venice.
