Unfortunately, I did not take advantage of this tip last Disney vacation- but my friend did and it was well worth it!

You know a one day pass is the most expensive to Disney and then by day 5 it's about $6 to add another day?  Well...if you get the tickets without expiration dates, you can save yourself a crazy amount of money!!  If you know you are going for 4 days in March, but may be planning another trip next year, get an eight day pass!  You'll buy four days for extremely cheap!
