Thanks Jen! So you are not telling your kids huh? We aren't telling ours either! We were going to tell them AT the airport, but since they will make a HUGE scene over it, we thought it might be better to tell them before. So, we are telling them two days before at my dd's birthday party. Their goodie bags will tell them...we got them Autograph books so far and still have to come up with some more ideas.
