Hi florida sun!
We've done the "ridiculously early" last day on each of our previous three cruises but we didn't find it too bad (except for having to wake up that early!). The whole routine takes about 15mins if you get there right on time. Each time, we've gone back to the cabin, DH and DD went right back to sleep and I sat out on the verandah with coffee and danish and watched the activity at the pier as the reloading started for those lucky people coming after us!
We've also done the "off ship/airport/home/work or school next day" which hurts (and we have to contend with the M25 too, Andrew Derek! Not the Dartford Crossing but the roadworks - we live just off J13 where it really is the biggest car park in the WORLD!) But, as you know, we're off to RPR at Universal for four days afterwards this year - getting excited!
Hope you and DD have a WONDERful time!
Diane
