Just found your PTR and I'm joining.
I can totally relate to your Disney depression, because that's why we booked our trip November 2011.
We really shouldn't have spent the money and DH is still moaning about our credit card payments, but honestly we both agree it was our best trip yet.
And we surprised ours on that trip too.
My DD(8) is also a girl scout and worked like a dog to get to 200, but was our troop top seller. Our area is super over saturated with girl scouts. She would have loved to get to 500 but I told her I don't think that's ever happening.
We did the Family Magic Tour last January and it was fun. It was only our family on the tour but multiple families can book at the same time. I honestly think it is more fun when you have more people. If you wound up being the only family on the tour, I don't think it would be as fun. Hope this helps.
