Hi Sarah! Welcome back, we are so happy you are coming to visit Walt Disney World!
Memory Maker is amazing. I had the advantage of experiencing this new service last month, and I must say I LOVE IT!
Unlike Photo Pass Plus, Memory Maker is completely digital! Memory Maker is linked to your My Disney Experience account, so you never have to wait for a cd to be mailed to you, and no more turning in a voucher at the park upon arrival. Don't worry about losing any photo pass cards either, once memory maker is linked to your My Disney Experience, photographers can simply scan your Magic Bands. Photos taken at restaurant locations, as well as some attractions are included in the price. You can pre-purchase the Memory Maker for $149.00, but be sure to do so at least four days before you plan to arrive!
As for your lost reservation for the Bibbidi Bobbidi Boutique! I suggest you call (407)939-7895 and explain your situation. I hope they are able to find your reservation!
Enjoy every minute of your magical vacation! If you have any other questions, please come back and visit us again!
