I am all for email snooping to help strategize on how to deal with bat-chit-craziness and legal matters - been there, done that. If one is too stupid to change passwords, that is their problem. Heck, my X still has a picture of her and I as her display picture for Windows Messenger because she does not know how to change it.
It is only 2 extra days and I am sure Caleigh will have a blast with no long term lack of mommy syndrome setting in. I think your X is a stubborn mule and its all about control. Instead of offering swap time, you might consider offering her cash.
I'm sorry that you have to coparent with an idiot pompous ass that is terrible at negotiations. It probably is not worth getting a mediator involved for just this, but you may want to consider it for revising anything in the parenting plan.
