Hello!!!! We're in!

We were booked since last January on our 7 day cruise. We booked on board for the 10% discount. We're on back to back cruises - the 14th and the 17th - anyone else? Anyway, when the kids sail free came out, we saved $800!! Woohoo!!
Our kids are 13 (boy), 12 (boy), 9 (boy), and 3 (girl!). They know nothing of the cruise. We are going to Disney the week before and the kids are running the 5K and I'm running the 1/2 marathon. This cruise is my "congratulations" cruise!!! We're going to surprise the kids the morning of the cruise by setting out their clothes with tshirts that say, "My parents surprised us with a
Disney Cruise today!!" I hope I can keep the secret!!!
