I was going to check on this too. Please let me know if you find out. I will let you know if I hear anything as I am going to contact them too.
I got a response! Took 12 days to get this.
Here was my original question:
Hi
We are heading to WDW in November for my mom's 70th birthday. There will be 12 of us. We'd really like to do the "capture your moment" for some great family pictures, but I see the max is 8. Is there any way to make this happen? Can we pay for 2 sessions?
Thanks!
Here is their "answer". Total copy and paste from their website. At some point, I will call those numbers to see if I can get an answer.
Greetings Jake,
Thank you for inquiring about the Capture Your Moment experience, and a very happy birthday!
Our Capture Your Moment experience invites Guests to celebrate a special moment, such as a birthday, in Magic Kingdom® Theme Park for up to 20 minutes with one of our Disney PhotoPass® photographers!
At the start of your session, your photographer will meet you at Box Office Gifts inside Town Square Theater then escort you to a capture location that has a view of Cinderella Castle. Available capture locations will be provided by your photographer at the start of your session and are subject to change based on inclement weather and park operations. The maximum party size is eight Guests per session. You may be able to book consecutive sessions, based upon availability.
Please note that if Guests have a Disney PhotoPass® entitlement, like Memory Maker or a qualifying Annual Pass, they can download the photos the photographer captures during the experience at no extra cost. Otherwise, photos captured by the photographer must be purchased separately.
For more information or for booking this customized experience, please contact our Enchanting Extras partners at 407-939-7758, 7 days a week from 7 AM to 11 PM EST.
Thank you for contacting Disney Photo Imaging!
Sincerely,
Star
