Welcome back to planDisney, Keith! We are happy to have you here planning a visit to
the Most Magical Place on Earth.
Keith, as a guest who flies in from Pennsylvania, I appreciate your question and hope to help point you in the right direction. A popular choice and one I have used myself is Mears Connect. A quick internet search will give you more information including booking online. Mears Connect services all
Disney Resort Hotels through a coach bus which doesn't require car seats.
Another option would be a car service. While I personally haven't tested this, a friend uses Quicksilver Tours which has the option of a 10-passenger van with car seats.
While my kids are just past the car seat stage, for years we needed to factor this in when considering transportation and I hope this helps in your planning. Keith, as you continue planning, make sure to check out the
Panel Extras of the planDisney website to view Pocket Guides for the different Disney Resort Hotels. These are great quick references to familiarize yourself with your resort before you arrive.
If you have any additional questions I hope you'll come on back to planDisney.
Wishing you a pixie-dusted stay,
Lauren
