Gail, I may be mistaken, but I thought that the All-Stars and AKL are in Osceola County, are they not?
I don't know if the resorts charge local sales tax on passes, but if they do, then it would stand to reason that those resorts would charge the correspondingly higher Osceola rate.
As to me, I always buy my hoppers in advance, at either TDS or
AAA. Sometimes if there has been a recent price increase, AAA will have the better price, but usually they are both the same, 5% off gate. (I've been told that since AAA is a reseller, they will sell remaining stock at the price corresponding to what they paid, so even after a price increase, they will honor the old price on tickets already in stock when the increase went into effect.)
