Thanks to everyone for the info. For anyone interested, I booked the tour this morning by calling 407-WDW-TOUR and had no problem reserving it for September 2004. Tours were available at 8:30, 9:00 and 9:30. The charge is $58 per person, but it goes down to $49 if you use a Disney Visa card (there are probably other discounts available, as well). The actual total charge for 2 people was $98.60. They charge your card now rather than waiting for the date of the tour, but a full refund is available if you cancel at least 48 hours in advance. Photo ID is necessary at check in, and they asked for the names of all people in my party. I hope this information is helpful to anyone else considering the tour.
