Thanks for the explanation zuzu although I will have to re-read it tomorrow to comprehend it. We just arrived in San Diego and checked in at the hotel and I'm so tired from the long day that I can't even think straight.
We left Daytona at 11:30 for an hour flight to Atlanta; then we had a little more than 3 hour layover in Atlanta before the flight to San Diego. Although it's only a little after 8:00 p.m. here my brain and body are on eastern time and after we get a bite to eat I'm going to bed!
