But it's not cost-effective to buy the one-day base passes from Disney as part of your qualifying package, then buy the rest of your tickets from an authorized reseller.
Example ONLY, prices not accurate: Say a one day adult base pass is $80.
You're going for seven days, so you purchase a six day base pass from UCT for $220.
Your total ticket cost per adult is $300.
OR - you buy a seven day adult ticket as part of your package. Disney charges you $225. Total cost per adult ticket is $225.
Sure, you have the one day base pass to apply to the purchase of a longer/more expensive pass on a future stay - but will you? Or will you keep booking packages and never use those tickets? Or will you even know where they are five years from now?
Also, ALL conditions/requirements for any BounceBack promotion will be availaible in your Disney room - if not on paper, then undoubtedly on television.
