I'm torn between having my son and I each bring a carry on and a backpack or just keeping it to one carry on and a suitcase. Because of air restrictions I hate the thought of only bringing one travel shampoo each as that will not last for the 6 days total that we'll be gone (4-day cruise plus a day before and day after spent in Orlando). On Sensation do they provide shampoo and conditioner? We also have a 1/5 hour layover between flights both flight days and lugging things around the airport terminal while we endeavor to eat between flights is something I'd rather not do. For those who have managed to fly to a port to cruise and only used carry-ons, what are your suggestions?
