Not sure if this was mentioned before in your other thread, but there is no bus transportation between parks. CMs are very helpful if you want to know the best way to go between parks. Don't make the mistake we made on our last trip. We took a bus from our resort to Epcot in an effort to get to the Boardwalk. We were planning to transfer to a Boardwalk bus from Epcot, because the Epcot bus got there first (we were going to take Epcot or HS). We had parkhoppers, but our traveling companions did not and we had already been to a different park that day so they could not cut thru the park to the International Gateway. There was no bus to the Boardwalk from Epcot.

It was very frustrating. I think we ended up taking the boat to HS and on to the Boardwalk from there. We wasted a lot of time on that little outing.
Also, my DH would not let me drive to DTD because he swore parking would be bad, but it wasn't. We took the bus there and coming back we took the boat to POFQ then caught a bus to the park we wanted to visit. We had stayed at FQ on our last trip and I wanted to visit again anyway, so it worked out. If we drove, I probably wouldn't have gotten to go there, so it's all good.
Also, if you have a GPS, it takes a lot of the guesswork out of it.
