We are going Christmas week and staying off site. I have no idea how fast passes work? We have little ones with us (2 yrs) and also a 5 & 7 years old who will be happy with the older little people rides like the tea cups, it's a small world, etc. so, do we need fast passes for even those or just the more popular rides for the older kids? I feel very overwhelmed and unprepared. Please help!
