Yes, but be aware carry on has limited size (and after Sept. 11th, it may be more enforced than normal... not sure). But with 2 suitcases a piece (my 6 year old daughter only needs one), we use the extra for packing soda, bottled water, beer and alcohol (bubble wrap a must for any glass bottles). You may want to pack a bottle of wine for a romantic evening. Enjoy your cruise!!!
