This will be our first trip to disney-we are going Dec 8-12. our kids are 5, 2 1/2 and 1. I am thinking that most of the rides sit 2-4 people-can I sit my daughter on our lap, or does she need to be actually strapped into a seatbelt? (I am thinking kiddie rides, obviously not coasters!!). I was wondering about the safari though, will they let me put her on my lap?
