It has been a while since I've used TiW for a dinner show, but it was 20% off the entire bill...but times and seating categories were limited. Usually the latest show of the evening and tier 2 or 3 seating, but that may vary seasonally. Ask when you call to book.
For any participating Walt Disney World restaurant where reservations are pre-paid, please make a reservation and pay full price at the time of booking. Upon arrival to the restaurant, present the Tables in Wonderland card for a 20% refund.
For the Hoop-Dee-Doo Musical Revue, the show times are 4:00pm, 6:15pm and 8:30pm.
From September 30, 2012 through March 7, 2013, the Tables in Wonderland discount will be offered only at the 8:30pm show.
From March 8, 2013 through August 31, 2013, the Tables in Wonderland discount will be offered only at the 4:00pm show.
From September 1, 2013 through September 27, 2013 the Tables in Wonderland discount will be offered only at the 8:30pm show.
Tables in Wonderland discounts for show times are subject to change without notice.
We just did the HDDR in June and when we checked in I asked about how to get the TIW discount and the CM told me to go to the ticket window to have them do the credit, which they did.
