Disney's marketing is so successful that they don't NEED to provide toll-free numbers to the general public - so why would they?
Figure it this way (example only): Somebody posted a similar request yesterday on the Dining Board, stating that they have to make 20 dining reservations. Multiply THAT times upwards of 10,000 Guests each day, and you see how much such lines would cost Disney and, ultimately, its shareholders (including many of your fellow DISers).
No, if we have to pay for the calls, we're more careful how many we make; more prepared before we call; and, after a couple of calls, one would expect experienced enough to press the 'right' buttons as soon as the options start being listed (instead of waiting through the entire recording).
In addition, many residential phone services include long distance calling - if not at this moment, it can generally be added cheaply (mine is $2 a month).
Most likely, Guests who express their feelings on this contact availability TO Disney might be advised to deal with a local
Travel Agent.
