Hi! 10th consecutive trip to WDW begins OCt. 13!!!!! We always pre-order Photopass to get the discount. Haven't thought much about the new PP Plus til now. OOPS! We've missed the 14-day window to order "Plus" and get the discount. QUESTION--Could we pre-order the regular Photopass with discount for $119 THEN UPGRADE to PLUS when we get there? If so, would the upgrade be $50 (to make it $169 the pre-order plus price anyway) or $80 (to make it the walk-up price of $199)?!!! THANKS SO MUCH!
