Our one o'clock appointment tomorrow is actually at two. It's three hours. I booked a 5:45 ferry. Too tight. So this morning I booked a second reservation for 8:15. The $17 fee is less than a hotel because we're stuck here.
24 hours of parking at Children's is $14.25. We sat at a soccer field yesterday for an hour so that when timed right we only needed one parking pass for both days ;) We left today with 15 mins to spare.
