Hey Cap,
We're thinking of the FL-CA cruise as well. That would be nice to see you there. Most likely we would fly to FL from Flint (I know you are closer to Detroit Metro), and then fly back from CA. I don't know what we'd do about cars at airports. Flints parking is a whole lot cheaper than Detroits, but we may have to fly back to Detroit from CA. We'll see. My BIL and his family are in San Diego, so we'd spend some time with them after the cruise.
Most likely we'd get a one way rental to Port Canaveral as well. It was our cheapest option last time.
Hope to see you on the cruise.
Juli
