Thank you. I too wonder why they don't have a toll free number, but that is the way it is.
1) It is really quite simple; there are two main reasons
. . . the number of WDW options
. . . people calling frequently to change things (eateries or resorts)
2) With the number of options, calls take a long time.
3) Other hotels can offer 1-800, because you call for a room and that is it.
4) At WDW, they have to go through a lot of options for rooms, views, tickets, packages, etc.
5) As for changes, most people change things at least once.
6) Many people change things A LOT.
7) Thus, WDW would pay for 1-800 service for no revenue.
8) Once the sale is made (original ADR or ressie), changes add no more revenue.
NOTE: The excuse that vacations are already expensive will not wash. WDW wants to make as much profit as they can, so avoiding the hundreds of thousands of dollars for 1-800 numbers in one method.
