It's too early to really know what the rehab schedule will look like in May, other than we know that the Rivers of America (Tom Sawyers Island, Mark Twain, Columbia, and Canoes), Fantasmic!, and the Train will be closed. The Hyperion theater will also be dark (probably - the new Frozen show is slated to debut in the summer, but they haven't specified a date). We may not know if anything else will be closed until much closer to the date (e.g.m anything from 45-day/6-weeks to just a few days in advance).
