You do. End of term 'screenshot' exam coming up shortly.

You're too kind.

Oh they do indeed.
You can most definitely use it 3 hours later, as Goofyluver said. We did that all the time on our last trip. It gave us so much flexibility. Disneyolic mentioned Soarin' and I agree - apparently they don't look too kindly there on late FPs. In general though it's not a problem. Nobody said a word to us last year so enjoy!
Yes, those things are the best! Most of our babyswap passes weren't dated at all and the ones that were said they were valid for up to 3 months. Can't say fairer than that.
Oh they're great! Babyswap passes are available on rides with height restrictions. You tell the CM at the start of the attraction that you have a child too young to ride and he'll give you a pass which is like an FP. Then you can go off with your girls (whichever of them isn't riding) and do something else and go and use the babyswap pass later for your turn. Let's say RahRah wants to ride with Dad, well she can ride with you again later cause you can take up to 3 guests with you using the babyswap pass.
Also, the babyswap pass can impact your need for FPs. Let me explain.... let's say you, DH and RahRah want to ride Splash Mountain but Boo bug and 'Baby' don't. Okay that means that you only need 2 FPs (for DH and RahRah) cause you'll be using the babyswap pass for your turn and that's *all* you need to get both you and RahRah on the ride. Therefore (and sorry if I sound totally over-the-top dorky about all this detail

) when FP time rolls around and you go to get your Splash FPs, you could get just 2 FPs for that but get 2 more for Winnie the Pooh so as to maximise your FP opportunity. See? We did that a few times except with us we had 4 park tickets and we only needed 3 FPs for the bigger rides so I would sometimes grab a single FP for Winnie The Pooh or Philharmagic to take DD on later!
Does that make sense????
Edited to add: Cathy, just to clarify, the CM at the start of the ride needs to actually see the child/ren who are too young to ride. You can't just tell DH to tell him! Just thought I'd make sure you knew that!!!
