The Walt Disney World Dolphin is a resort hotel located between Epcot and Disney's Hollywood Studios in the Walt Disney World Resort in Bay Lake, Florida, and across from its sister resort, the Walt Disney World Swan, both of which are operated by Marriott International. It is one of the few resorts inside Walt Disney World that is not owned and operated by The Walt Disney Company. The resort opened on June 4, 1990, partially in response to a lack of convention center space inside Walt Disney World.
