My goal is 1 suitcase and 1 carry-on per person (family of 4). Last time, we took 5 suitcases, but we did have extra clothes because we were spending a week in WDW post-cruise. The formal wear and shoes takes up one large suitcase. Then, we'll have a suitcase for beach things, including snorkel gear, and 2 additional suitcases with the rest of our clothes. And yes, we do mix and match!!!!
