And if you call and they say no you can't, call back the next day and say "I added the dining plan yesterday, and when I looked at the total price it didn't seem right to me, so I wanted to check on it." Then they'll look and say "No, that is right, you have X number of people and it totals to Y" and you say, "Oh, no, we should have Z number of people." And they'll say "Oh, let me check" and they'll read out the number of people on the reservation, and when they get to the two-year-old they'll say "Now, she is two so she doesn't count" and you say "OH! that's the problem, she had a birthday" (and that isn't a lie exactly, she did have a birthday) and they'll say, "OH, let me fix that." And they'll mess with it for a while and come back and say "OK, now you have the dining plan for Z number of people, and your new total will be Q. Is there anything else I can help you with today? Do you need to make any dining reservations?" And you say, "No, that's it," and they'll say "OK, a new reservation confirmation will be mailed out to you reflecting the new totals, have a magical day." And then there will be that awkward second when you wonder if you should really hang on for that second to do the survey.
