After I sign into "My Disney Vacation" (upper RHS of disneyworld.com homepage), I click on 'Dining Reservations' at bottom of that drop down menu. The next screen that pops up has a single row (of 2 input boxes for ADRressie#/phone#.) Directly below that in blue letters, it says '+Retrieve Multiple Reservations'. When I click on that, another row of input boxes appears below the previous one. (I've only ever clicked up to 5, so I don't know how many it will list at a time.) I can then list all my ressies/phone number and when I click 'Retrieve Dining' button (to the right of the first row), it will then list all my ressies at once. I don't know a faster way to do it than this though.
