I took my family the week before Thanksgiving, and we had a great time. We would rope drop in he morning, and then come back after an afternoon rest. Never waited in line more than 20 minutes.
We love the service, and feel it is worth the cost. It is quick and easy to use the service, and you do not have to worry about carrying your own device. You can quickly see your pictures on your my Disney account.
Rider Swap can work that way. We had to show the child that was unable to ride the attraction. They than gave us a rider swap card that was good for up to three people. I asked why for three people? The cast member told me that three people can usually ride the attraction in the same row...
I would do QS, and do 1-2 character meals. We found it difficult sometimes to manage ADR with young kids. Getting kids to point A to B can be overwhelming and opening your schedule with QS meals made our life easier.
We love it! Especially with young children you don't have to worry about your own camera. It is so easy to walk up to one of the photographers to get your photos. It is great for getting pictures from the ride as well.
Line quickly builds up at PP. We RD and when we arrived we had about a ten minute wait. The line quickly builds. I would go straight through the castle to get to PP. If your ADR is running late, I would head straight to BTMRR. We usually can ride it 2-4 times without a long wait.
I like Plan B. I found out with my young kids that the pool can wear them out more than the parks. I agree to do a QS lunch and hit the pool for a little before the party.
Cast Members were fantastic to give a FP when my daughter got sick at the park. They then handed us a paper FP for my daughter to return at a different time/date.
We were there in January as well. We were able to get FP's for TT and Soarin. We did a lot of refreshing on our phone and sometimes we had to search for 1-2 people at a time. It all worked out where we could get overlapping times.
