I don't have a box but like Rollerdonna I have a room. I don't call mine a " cruise " room but a " travel " room. As I look around me now I see the walls covered with those wonderful ( to me ) colorful Caribbean paintings , wood carvings, cups, and momentos from all over.
My daughter-in-law travels internationally in her work and brings me things from places I'll likely never get to visit. So, thanks to her and the trips and cruises I have been fortunate enough to take, I have a collection of stuff from Singapore to Germany to Africa to the Caribbean. Heck, I even have something from Florida. I also keep photo albums and along with photos I keep what some might think silly, such as tickets, sail & sign cards, brochures, etc. It's fun and helps on a cold, cold day like today.
