I know you will have a great time.
I too have been seriously looking at Disney for a cruise with the grandkids but "Grandpa" is having a hard time swallowing the price. Grandpa is a spoiled brat and must have a balcony cabin and $9,000+/incl air is too much for grandpa to open his checkbook for. Grandpa can do Oasis for half that amount.
BUT the kids keep asking: "When are we going on the Disney ship?" Grandpa can only take that so many times until he gives in.
