There's been no mention of any changes to the Deluxe Plan from any of the UK travel agencies. However, these changes were announced with our Free Dining offer, so they were mainly concentrating on the QS and Regular plans as that is what we're offered during Free Dine; I don't know whether the Deluxe plan will be included in the changes or if it's been left out because it's not being changed at all! I'm sure we'll know more once Disney release the 2017 plans officially
In the description of deluxe on this site http://www.virginholidays.co.uk/special-offers/disney-dining-plan, the table service doesn't include an appetizer, maybe it was a mistake?
