I'm going to WDW early May. I haven't been that time of year before and never needed rain coats. I was curious if I get disposable rain coats does it typically just rain one time a day so 1 a day is plenty? I'm thinking it will be too warm to want to carry around something reuseable and no young kids so no need for a stroller/backpack so thinking disposable rain jacket would be easy to throw in a purse.
