Just saw this on the Disney Dining Page and I think I may have to try and book this! It will be on Wedesdays, Fridays, and Saturdays from 7:45-9:20 and allow you to taste desserts and wines from around the world. There is also a special viewing area for Illuminations. It is $49 for adults and $29 for children and bookings began on the 12th with the first party to be on the 15th of March.
