Hi Peggy,
I have some great news for you!
You do not need to pay for the Hoop-Dee-Doo Musical Revue at the time of reservation if you are on the Disney Dining Plan.
To avoid this, you need to firstly click on where it says 'I want to use my dining plan to book reservations' which you will find at the bottom left hand side of the 'Make a Reservation' box as seen
HERE
You will then be taken to a page where you will need to enter your resort confirmation number, last name and arrival date.
Once this information has been entered you will be able to make your reservation for the Hoop-Dee-Doo Musical Revue without having to pre-pay.
Please note that two table-service meal credits will be required per person for those guests using the Regular or Deluxe Dining Plan but only one table-service meal credit for those guests using the Premium or Platinum Dining Plan.
Wishing you a magical trip!
