I am sure many have, but we haven't. We will be needing one for my husband on an upcoming March 2010, cruise. This is a situation that has come up rather suddenly, and I am so ignorant about these issues. I am sure that we can take it on the ship, but is there room to charge it every night in the cabin? I am particularly concerned about having to possibly "skip" the day at Castaway Cay (Disney's island). Can anyone shed some light on this for me? And does anyone have recommendations as to who you can rent from? I know who we rented from just recently, when we were staying at WDW, but if we rent from an agency in Orlando, can we take it on the Diseny transportation from the airport to the ship? Too many questions, I know, but I would really appreciate any info you can give me. Thank you.
