I share your optimism...Disney has a pretty amazing track record for customer service and I cannot imagine that it will be anywhere near as awful as many here seem to think....will it work right 100% of the time from the getgo?? No, probably not, but does anything??
Let us know how it goes for you but I am banking on the fact that a lot of people will be pleasently suprised.
When I think of the hassles we have had over the years with rental car lines and late/missing town cars (all at considerable expense, I might add) I think ME is going to be a delight.
I have watched with great interest on the Disney Dining Forum how the prophets of doom bashed the MYW dining plan, how it was going to be such a rip off and no one would ever use it that knew what they were doing, etc, etc...and after a few minor start up snafu's the reviews now are all glowing...everyone that has tried it seems to love it...I strongly suspect by this time next month the same will be true of ME!!
Have a great trip!!
