Ok, after reading everyones postings about WDW trans. vs. rental cars, I'm beginning to rethink our strategy. Maybe we might not rent two cars (substantially cheaper than 1 mini-van!!) but take a shuttle service to the parks. We don't plan on leaving WDW once we get there anyway. And we could save some cash. We are 4 adults and 2 small children.
How do airport shuttles/limos work with small children that need car seats? I'm a car seat FANATIC and have two kids who still require them (older is in a booster). I will be bringing one for my smaller child to fly in which converts into a booster for the older once we land and was going to rent a regular car seat for the younger kid at the rental car company so we would have two seats with us for driving. If we don't use a rental car, what do the limos/shuttles do for small kids? I'm not very comfortable letting my kids ride in any vehicles without car seats (FLA law or not - mommy has her own laws!!).
