You don't have to do that. I just made my dining reservation this morning and didn't say one single thing. The questions are yes/no. "1" is for yes, "2" is for no. If I can remember the questions, the first one is for English so press "1" for yes (or "2" for no). Then I think it asks if you are in the Orlando area or if you need reservations in the next seven days, press 1 or 2 for yes and no. Then I think the next one is if you want Victoria and Albert's so "2" for no (or "1" for yes). Those two questions could be reversed. When it gets to the "if you've been here five times" or whatever, I just kept pressing "1" for yes because that applied to me for all the questions.
So you can press the numbers if you can remember "1" for yes, "2" for no. And you can press the numbers as soon as the question starts being asked.
