The parks and 3 onsite hotels are all within walking distance, or there is a water taxi. It is a short walk. The bus referred to is for if you wish to go to Seaworld or an off site area. Citywalk, the three hotels, and two parks are all onsite and no transportation is needed. We went last fall without the kids and have a trip planned for this year with the kids. I think kids will enjoy the park a lot, though some areas are not for the smaller children. It takes about 3 days to do the two parks completely, so 4-5 leaves time for relaxation, pools, seaworld, and re-doing anything you missed or liked a lot. The cheapest ticket would be the five day consecutive day pass for $89, or look at the links on the threads below for the Kraft offer where you get the 5 day pass for $82. It is really a bargain. Also, once you have used the Front of the Line by staying onsite, it will be hard to go back to waiting in line anymore.
