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%.
In regard to the OP's question, the 6.5% sales tax on the tickets and the 6.5% (or 7.0%) portion of the tax on lodging would be includable in your calculations for sales tax. The 6.0% lodging tax component of the total lodging tax is not deductible. And I do this myself for my own travels.
