Some things that Lee forgot to mention... Parking:  If you wait till the last minute to get there, you are gonna either be walking several blocks (or riding the bus if you get one of the places right by the free shuttles) or paying the little bikes to take you down.  Just an FYI, I showed up one year at 6 am, and got a spot at the parking structure right next to the convention center.  By 7:30 it was almost full.  Food:  There is a Safeway that sells fresh sandwiches and soup, as well as a variety of other deli items.  Great place to eat, but they close early.  Get there around 11 if you want to eat there.  For good Italian food, there is a Buca Di Beppo a short way from the convention center, but bring a friend if your going there.  Another good place is Dick's Last Resort (off the wall place, as the waiters and waitresses get to be a jerk to you, but the food is decent).  Water: Yes you can suffer heat stroke in San Diego.  Especially during the summer, so make sure you carry a bottle of water around.  Keep hydrated.  As for the hotels, if your not booked by January, your probably not gonna get anything close.  My suggestion, try Escondido, Temecula, El Cajon.  If your lucky you might find something out in Fashion Valley, but this is doubtful due to the rising gas prices.  If your military, 32nd street is just a trolly ride away from the Center.  You might wanna think about parking either on-base, or at the Navy Exchange, as these places tend to be monitored better than the rest of the San Diego area combined, and are pretty much safe from people messing with your vehicle.

You know what?  if I dont post this soon, I am gonna just give everybody a San Diego Comic Con survival guide, and spoil everyone's fun.  I am gonna shut up now.

Just some friendly tips from someone that has gone for the last several years.

See ya in San Dog.
