You can find them at the resort gift shops as well as the parks. When it is raining out, the cast members working in the gift shops usually display them, otherwise just ask a cast member for them. But I honestly would buy a bunch of cheap dollar store ponchos. Disney ponchos cost about $10+ and rip and do not last as long as you would like! They rip especially around the neck/hood area. Not worth it. Seriously, buy some at the dollar store and bring them. Will cost you less in the long run!
