So we are planning another spring break trip but this time with extended family and I would love for my younger sister to come along with her family but she is on the fence about going because she has a baby that will be 16 months old at time of the trip (her other daughter will be 5 years old at the time of the trip). She has never been to WDW with her family and thinks waiting until the baby is at least 2 years old might be better. Is there a real difference between 16 months and 2 years old when it comes to a WDW vacation? My kids are older, but I am trying to tell her that there isn't much of anything different they will be able to enjoy at 2 rather than at 16 months. As much as I would like for my dear sister and my nieces to be a part of this trip, I don't want to push her if she thinks it will all be a total flop if she brings a 16 month old. What do you all suggest?
