Combining FP and Child Swap?

[Sean's momma]

Also, IF this works, then technically I can get DH and DD1 a FP and Myself and DD2 a FP for different rides, use the Swap and then all 4 of us ride 2 rides?

Looking at the OP it apppears she has a 2 year old, if said daughter is still 2 when you go to DL, you wont be able to get a FP using her because 2 year olds do not need tickets. Now if she is 3 and you buy a ticket then you can get a FP. I hope this made sense.
