I can only speak for DL, as that has been our only experience. I actually like the kiosks. It does mean more walking, however, we use some of our wait time.
We actually enjoyed the alternate wait place and used it to our advantage. For example, California Screamin had a 50 minute wait. We got it on our
DAS card in DL, had lunch, and then walked over to California Adventure and walked right into the FP line for California Screamin. We arranged the attractions with the longest times around either a show, a meal, or rest times. Not a big deal.
I am sure you will do figure out what works best for your family. I was extremely nervous before our trip, but, it worked better for us than I anticipated.
Oh, just a tip: the line at GR at DL was extremely long in the morning. One thing that worked for us was me standing in the line and texting my DD when I moved up on the steps. My DD stayed around - visiting with Character's and at one point went and looked in the Eporium. My DD is older and this seemed to be okay. If that is not possible, have a member of your party stand in the line. Also GR in California Adventure doesn't seem as long a line. You could also send a runner for FP to World of Color and Radiator Springs.
Another tip: It was not worth it to get a DAS time if the standby time was less than 20 minutes.
