Under your
MDE account, there is a tab called my tickets and reservations. When you click on it, there should be a tab to link room reservations and a tab to link tickets. When you book your room through David's, the owner that books it will give a reservation number - that number can be linked to your MDE account. Your tickets can be linked independently of your room reservation. You can buy your tickets through Disney or
Undercover Tourist or whereever - all can be linked through MDE. If you are getting the
Disney Dining Plan and you are renting through David's, the owner is going to have to add the Dining Plan. The dining plan is linked to your room reservation - I am not sure if it shows up in MDE or not (though you do not have to add the DDP to make dining reservations).
