No, it hasn't gotten any busier as of this past May when we drove 429 to FW, and back out heading home. Exit 8, off 429, takes you into the back entrance to WDW. Also, there was a lot of construction going on right by exit 267A of the Florida Turnpike, onto Toll road 429. There is one toll plaza on 429, I think it was $1.50 for a car.
