I will be arriving Friday afternoon around 2PM and be leaving Sunday night after the Con. I'm guessing the big Watchmen day is Saturday.
I'm staying at the Hawthorne Suites - its about 3 miles from the Con. I could walk, but I'm guessing I'll take a cab or a shuttle bus if they provide one.
Waylayer - which Sheraton are you at? Is it walking distance from the Con?
Check the comic con website, there's a link to a map of the shuttle paths to see if your hotel is near one. I don't think you'd want to walk 3 miles in the San Diego summer heat. :p
The Sheraton is 4 miles away, up on the highway northwest there on the bay. It's not on a bus line, unfortunately. I've been calling hotels closer to downtown that are on bus paths and closer to the gaslamp district which I'm sure I'll be checking out on the nights, as I have a friend who lives in San Diego who'll probably want to show me around. I originally was going to leave Wed. night, but now I think I might change to go Thursday morning, and go to the Con on Friday and Saturday as well. I'm planning on driving up to LA on Monday and visiting a friend there for a few days afterwards.
EDIT: The Sheraton actually does have a shuttle bus. Check this: http://www.comic-con.org/cci/forms/cci08_shuttle.pdf
The hotel is #31 on that list.
I decided to book my first choice - Best Western Cabrillo Garden in downtown - it's near #9 on that list. I think it will be more funner. : )
