I believe there is a special Easter theme to the parade... but just that Mr. and Mrs. Bunny join and there are some other special parade touches. We were there Easter Sunday last year and missed the parade as we headed to Epcot. Mr. and Mrs. Bunny were also there doing a meet and greet... the line was very long and hot. There were also egg hunts going on in the UK pavilion in the garden which were cute to watch while we waited in line.
