Let's not take the gas pipe yet, folks. Considering that there are far fewer kiosks than fast pass stations, and that FP+ takes much longer than FP- selections, I think it is very unlikely that Disney expects all of site visitors (the majority) to make day of FP+ selections at a kiosk. Also, that patrons at the Swolphin were singled out suggests this is a testing thing using limited capacity.
No, the biggest problem with any new technology is the fact that people just don't know how the heck to use it! My god, let's face it, If DIS'ers are having so much problems, what's going on with the rest of the population. Try to teach my Dad how to use his new Harmony remote, I dare ya!
I think that there will be a number of people that will come to the parks, never used FP+, heck, never heard of FP, and will need help. The reasons the Kiosks are empty is because there is still FP-, wait until that goes away..
I think this is just a capacity test, which I think will fail miserably, even with the 3-5 thousand Swolphin users...
