I think I'll pack a small one, just because I wake up a lot during the night and like to check how much longer I have to sleep.
But that is a good idea to use the wake up call.
I'll let you know how we like it! I think I have literally spent more time researching cruises/ships/ports/excursions, before and after we booked, than we are going to actually spend on the cruise. We're going with a big group - me, dh, our 2 preschoolers; my in-laws, and my family...20 in all, and 3 generations. So I guess that's why I want to be as prepared as possible (since I'm doing the planning for all of us basically). We're counting down the days!
