It's at Ariel's Grotto at the beginning of Paradise Pier, from 10:00-11:30 am. From roughly 10:00-10:30 and 11:00-11:30 it's Sailor Mickey and swimmer Goofy. In the middle it's sailors Chip n Dale. We went twice, on different days, to see each.
Many thanks! I spoke with two different DLR CMs on the phone and neither knew. Wanted to find out before our day at the parks so I could work it into our plans.
We also saw Max with Mickey and Goofy when we went. We had a great time because we were the only ones there and the characters spent 10 minutes with us.
