The most recent addition to the Swan and Dolphin complex at Walt Disney World is the Walt Disney World Swan Reserve, which opened its doors in late 2021 and has become a staple of the Epcot resort area by 2026. However, as of March 2026, the "new" major project is not an entirely separate fourth hotel, but a massive $275 million expansion and renovation of the existing footprint. This includes a striking new 100,000-square-foot convention annex being built at the Dolphin, which is scheduled to open in late summer 2026. This annex adds the "Upper Peninsula" and "Lower Peninsula" ballrooms and multi-function spaces, effectively turning the Swan, Dolphin, and Swan Reserve into one of the largest convention destinations on the East Coast with over 450,000 square feet of meeting space. While rumors of a fourth "boutique" tower occasionally circulate in 2026 development circles, the current focus remains on this massive structural transformation that preserves the original Michael Graves architecture while modernizing the guest rooms and tech infrastructure across the entire Marriott-operated resort complex.
