So, we won't have a car this time around, but will need carseats. My son is still in a highback booster (7) and daughter is in a 5 point harness (5). I am unsure how to tackle this without using the minnie van option which seems really pricey. We will need transportation to and from the airport, and I am thinking that we will need 1 other trip to Disney Springs and then potentially an early trip to MK for EMM (i'm not sure resort transportation will be running early enough). We're staying at Swalphin this trip, if that makes a difference. Just looking to see what's worked for others who have kiddos in seats, without renting a car.
