The green and black-roofed structures are believed to be expanded queues, designed like a greenhouse with raised, glass-panel roofs.
The back side of the expansion is where you’ll find the entrance to Remy’s Ratatouille Adventure.
Given progress on the expansion, and the appearance of the expansion on maps promoting the EPCOT International Flower & Garden Festival, there is a chance that the attraction and expansion may open before the festival ends on June 1st. That could accommodate crowds coming to visit for Memorial Day weekend from May 23rd to the 25th, considered by many as the unofficial start of summer. However, due to the unprecedented park closures, it is unknown whether the attraction will open on schedule for its Summer 2020 debut.
