Any prices published by Disney do not include sales tax. The sitres, including this one and allears, do not try to modify prices to reflect tax.
The basic Sales Tax rate in Florida is 6.0% and is on most goods and services. The counties have an option, by vote of their residents, to add a surtax of 0.25%, 0.5%, 1.0% or 1.5% to the state rate.
Orange County, which is most of WDW has a surtax of 0.5%, so purchases (including meals) are taxed at 6.5%.
Osceola County, which has the All-Stars Resorts and Wide World of Sports in it, has a 1.0% surtax so purchases at those locations are subject to a 7.0% tax.
In addition, counties are allowed to have a tax on transient lodging. In both Orange and Osceola Counties it is 6.0%, so all lodging except the All Stars is 12.5% while the All Stars, in Osceola County, is 13.0%.
