My mom and I booked our upcoming February Disney vacation a while back. We got the Stay Play Dine deal at Riverside (garden view) with 8 day PH. We recently got our flights for less money than we originally paid so got back credit and were thinking of taking someone else with us. She is 16 and when I added up online how much it would be to add her to the package, it comes out to roughly $497. When we phoned Disney and asked them how much it would cost, the representative told us around $600. Does anyone know why there would be about a $100 difference between what price I get and what Disney is giving me over the phone? We did manage to get ours before the price of the deal went up about $100 so not sure if that would be it our not. When we booked ours, it cost $2,638 (we opted for the Disney insurance since it saved me in the past when I got sick during a trip and paid the whole hospital bill. Without the insurance, it would have been $2,486. When I price the deal now, it comes up as $2,576 (without insurance) and to add the extra person on (under 17) it would be $3,073 (without insurance) which is a difference of $497.
