OK Captain Mike, on your advice I booked a room at the SD Marriot Suites Downtown at Symphony Towers for Saturday night. (I can't fly in until then, but I'll try to be early.) I won't have a car, so I hope this location works for getting to/from planned meals or activities without incurring the national debt in cab fare. On Sunday I will move out to Loews Coronado for three more nights, but I figure I can go back to the airport and take the Cloud Nine shuttle from there. I've used them in the past, and they've worked fine.
