I'm here! You guys are going to have an amazing time! All of your shirts and other goodies look great. Amy's transfers truly are the best, and worth every penny.
I would agree that if it were just your YDS, the trip wouldn't be as worth it. But your ODS is going to have the time of his life. My ODS loved it. Around day 3 I asked him, "Is Disney World as good as you though it would be?" And he said, "It's so much better!" Best answer ever! I felt like the trip was for him, and as long as my YDS wasn't unhappy, I considered it a success for him as well.
Since there are several who read my PTR about to go with 2-5 year old boys, I was thinking maybe I'd list my boys' favorite rides, etc. on there, if you're interested!
