I guess this remains to be seen, but my guess would be no. This special event is set up in a building between Canada and England, so it is not a "restaurant" and therefore is not on the MWY dining venue list. Maybe WDW dining will decide to add it to the MYW dining options just for Mother's Day. Anyway, if it is added, this brunch normally costs about $29.99 per adult so I think that would about equal one of the MYW full service meal options, when looking at the menu prices for those restaurants currently participating in MYW (A meal at LeCellier, Kona, etc could easily run more than $29.99 pp with appetizer, entree, dessert, drink and tip). BTW, I have done this brunch before, for Mother's Day in 2002, and I did not think it was all that special. IMHO, I think there are more special restaurants in WDW to celebrate Mother's Day.
