OK, weird question - I've never been to WDW when it was so wet I needed a poncho. April might be different, though. I know about buying disposable ponchos at home before the trip, but I'm inclined to gamble and just buy a WDW poncho onsite if/when I need one.
So, when the storm passes and I take off said poncho and want to put it away for later use, how big a ziploc bag do I need for it? Quart size? Sandwich bag? How small will it (easily) fold up? I carry a crossbody bag about 7 x 9 x 3, not a huge bag/backpack for stowing things, so I'm hoping the poncho will be easy enough to fold and stash when not in use.
