Is anyone really following the DIS FAQ packing list that closely? Do I need suction cups with hooks or plastic clothes pins? If I brought everything that is suggested I would be packing 12 suitcases! I am really really going to try for 3 large with a rolling duffel for snorkel gear. Can it be done? There are 6 of us. My MIL is packing her own stuff.
We try to pack minimalistically. Clothes can be reworn (wear a shirt first for dinner, then later in the week for daytime). We don't skimp of underwear. And of course, being female, I have to bring shoes

Most of the other stuff on that list is just in case sort of stuff. One thing that I always brink is a light up travel clock, as I can't stand not knowing what time it is when I wake up during the night.
We usually pack 3 rolling bags and a garment bag for the 4 of us. You're kids are smaller, so you may be able to squeeze it in, but you may wind up needing another bag. My kids know that if they want to pack more stuff, they will wind up lugging the extra bag around, so they somehow manage to decrease what they take.
