We are having ours at The Hilton- we also chose not to do an AI because we felt it was too expensive for our guests. Also, I felt like I was paying twice for food because you still need to pay for the cocktail reception and dinner at most places.
Anyway, we are budgeting for 60 people, and I am at about $25000. Hopefully won't go too much over that. You will find so much info on this site I am sure you can make it happen!
PS- I am in San Diego as well
