This is from an email I received from DLRP the other day:
"On March 17th, the 15th anniversary of
Disneyland Resort Paris goes Irish, as the fun and folklore of St Patricks Day will meet the wonderful world of Disney with Mickey, Minnie and friends celebrating Irish style. Therell be the St Patricks Day pre-parade down Main Street, USA, complete with a dusting of Disney magic, traditional Celtic music to dance along with and of course a dazzling display of Irish dancing. Be sure to save a few photos for the finale, as Sleeping Beauty Castle becomes a glow of green under dazzling bursts of fireworks."
We were there for it a couple of years ago and it was very enjoyable. There was even a band in the Village when the parks had closed, good atmosphere.
Hope this helps
