Self laundry. LOVE this option.
We all packed one bag per person for a 9 day cruise this past week. We did have RC do our laundry before we left the ship cause we were in need of clean items!
Roll your clothes, doesn't take that much room this way. Coordinate shoes so you don't have to pack to many. Keep it all simple. If you don't think you'll need something then don't take it at all.
