It is a hit or miss option to take a shuttle. It all depends on whether you're in a big hurry to get to your resort and whether or not a "grocery stop" is required. The new shuttle might be free but I envision it as taking a lot of time out of your first day, but if you're not planning on doing anything special the first day it would be a cheaper solution. I tried Mears the first trip in 1995 and we did have to wait for the van to get full, then stop at each resort which was fine since it was our first time and we weren't planning on going to the parks on the first day. Ever since though I've taken a car service to make the most of my day. HTH
