My family (13 of us) did the 7-day Disney cruise over this past New Year - what a blast!  Our daughter is 3 with SWCAH and loved every minute of it.  She would have spent all of her time in the Kids Club if we would have let her. 

I agree, get the insurance for the same reasons mentioned earlier.

As for meds, I’m sure I over packed, but I took an extra 30 days worth of cortef & florinef - 2 shot kits - in addition to all the pain, cold, cough, sneeze you name it medication.  I even took pedialite, just in case.  And my best advise is to wash, wash, wash hands when ever you can.

Take the cruise and have fun!
