Welcome to the Moms Panel Susan!
Sounds like you have an incredible vacation planned! I love Disney's PhotoPass Service. I checked with the PhotoPass people to clarify. This can be done if you do it within the allotted time frame.
From the first date a picture is taken on a PhotoPass, you have 30 days to claim those photos on the PhotoPass website. If your 2 trips falls within those 30 days you can add all photos taken to your PhotoPass account.
Here's something else to remember. Your 30 days to order your pictures starts tolling on the first day you view any of your photos. So if you go back to your hotel and pull them up on your computer or cell phone, your 30 days to order starts running. If you see that you'll need longer than the 30 days, you can purchase an additional 7 days (currently $4.95) or 15 days (currently $9.95) to order.
You can go to any PhotoPass viewing location in the parks or hotel to view the photos and your time will not start running. When you log in to your personal account, the time starts running.
If you see that you'll be cutting it close with all of your travels and need the maximum amount of time without purchasing additional time, don't view your photos online until just before the 30 days from the date the first photo was taken (just make sure you don't miss the deadline). Then log onto your PhotoPass account and upload your photos. You can upload as many PhotoPass ID numbers as you want from that time frame. That will then give you another 30 days to order.
If you haven't already preordered your PhotoPass CD, go to
www.mousesavers.com. They have a code on their website that will save you some money.
Wishing you minnie magical memories :-) Allison
