If you have been looking into buying discounted Disney World Tickets, then you have probably come across someone who is selling used, partially used passes.
Many folks are selling these tickets online at a "bargain" price, and a good number of vacationers are tempted by Disney ticket prices that are "too good to be true".
As with just about everything in life, it seems too good to be true, it probably is.
Here is why:   First of all, there is just absolutely no way that you can tell if a Disney park pass really does have a certain number of days left on it.
It is not until you get to the park and scan the ticket that you will know for certain, if it is valid.
By that time, it is too late.
  In addition, Disney World park tickets are non-transferable.
This means that everyone over the age of 10 has a finger scan when they use their ticket.
So only that one person is able to use the ticket.
Even if there are still days left on it, if someone else used the ticket before you, then you absolutely cannot.
  Lastly, and perhaps most importantly, in Florida, it is illegal to re-sell partially used tickets, and Disney does enforce this law.
  There are a number of used ticket brokers in the Orlando/Kissimmee area, and many are shady operators with small storefronts or desks in another business.
Most will try to sell you partially used passes that will probably prove to be invalid.
And it is sad for the unsuspecting tourist who now has a ruined vacation.
  When it comes to purchasing discounted Disney World tickets, let the buyer beware! Buy only from an authorized, reputable ticket broker.
