I have 3 parks left on each ticket for my family of 4. I don't see us needing park tickets till at least next summer. We go to Disney once a year and sometimes twice but don't always due the parks. Do I spend the $2311.80 tonight to buy 4 10 day non expiration with 10 fun visits or do I wait till I need them and pay a heck of a lot more for them. Please help....
