Wow. That is so responsible and I bow down to your preparedness. Try as I might to be "early" on my planning and packing, it rarely happens.i don't pack. As a previous poster stated, I have a suitcase ready with everything I need. When i come back from trips, I launder my "Disney" clothes and pack them right back in suitcase, ready for next trip. I always have ponchos, filter water bottles, sun hats, sneakers, etc. in suitcase, along with any meds or first aid. After years of going to WDW, you tend to build up an arsenal of clothes you'd never wear anywhere else!
