Welcome and hope you guys enjoy your trip!
Hotel Circle is a good central location also about 5 minutes from me. Those three places are a great list of some of the key attractions we have here. Our family goes to Sea World on a regular basis. Balboa Park is a nice place to visit and is where the Zoo is located. There are some great museums and historic sites to view there. There are some nice waterfront places to visit like Coronado, down town by the USS Midway and Sea Port Village.
Meeting up sounds great and I should be able to meet up for a drink on the 8th, there are plenty of places not far from where you are.
