They still have the option of 1)Add them to your cruise booking and pre-pay with your final payment. 2)Wait until you get onboard and then can add them to your onboard account. If you choose this, you'll get coupons to put in an envelope and hand to the individuals so they know you paid. Of course, if you tuck a little extra in the envelope with the coupon thats acceptable too. 3)Still can pay cash to the individuals.
The first time I went on Disney I thought "Oh, what have I gotten myself into." But I am very pleased to report the 600 children really weren't a problem. First, there is no casino on Disney. That whole space where a casino would be is all a children's area with video and hand on games etc. The programs for children are excellent and they keep them busy. Then you have the three different pools. Children aren't allowed in certain lounges after around 8PM. So the adults really have their separate places. Everything is Disney on the ship. You will see all the hidden Mickey's on the ship, like in the park. The movie theatre shows current Disney movies and the production shows are based on Disney with adult humor which goes right over the kids heads. The rotating dining is very simple. On the Disney Wonder you have Triton's, Parrot Cay, and Animator's Palate. Palo's is the reservation only restaurant. So on your boarding card it will tell you the first initial of the restaurant in the order you will go for the 7-day cruise. Ie: Richard Mattox Cabin 1027

It's been a while since I've been on Disney and I need to go again. I don't know if they are still doing it, but for a while they were having fireworks off the ship. They were the only cruise line to receive special permission to do that. I haven't heard anything about fireworks on Disney lately though. They did have some of the best soft Oatmeal cookies on their buffet!

It was also funny, the three times I went on them, the first day on the buffet they had these large shrimp. Then all the other days the shrimp would be substantially smaller! I really need to go on them again.
