18．Disney World was built with children in mind．However，without proper planning，your dream visit to Disney World could become an endless problem．A few tips can help both you and your children enjoy the visit．
Disney World needs a great deal of walking，and unless you arrive during the off-season，the lines are often quite long．That's going to make your children tired and angry．So make sure the kids have comfortable shoes and bring a stroller（婴儿车） if you have a small child．Bring along some snacks such as fruit or biscuits for times when they get angry．As for waits in line，it helps to have a few small toys to keep your children busy．
Disney World's parks all have rides for young children．They also have rides children should not go on-usually because they are not safe．For situations in which adults want to go on a fast ride such as Space Mountain or the Twilight Zone Tower of Terror，Disney has a"child exchange"system that allows your group to keep in line together-when you reach the ride，half of the group can take it while the rest stay with the children，then the groups exchange places．Think about each ride carefully and choose those that you feel are best for your children．
Nothing is more important than safety inside the parks．Children can easily become lost among the crowded and finding them again may be a toilsome thing．So be careful to keep your children nearby and always watch their location．
