Here is the thing to keep in mind - Disney is 51 square miles. You will have a limited amount of time. Travel time is time not spent seeing WDW (with the possible exception of taking the monorail). A trip from the MK to get ice cream at either Ghiradelli's or B&C will involve a 40+ minute trip (it isn't easy to come and go from the MK). If you want to return, it will be 40+ minutes back to the MK. You can easily spend 2 hours getting a sundae. Now you may say "so what" - everyone has different priorities and chooses to spend their time in different ways and if you are a huge ice cream fan, maybe this is worthwhile to you.
I'm telling you this because its your first trip and sometimes people have unrealistic expectations about how easy it will be to get around and how much they'll be able to accomplish in a week. Disney is about the size of Manhattan, which means you have to say "would you go across town in NYC to get ice cream." (Granted, less traffic at WDW).
It only after this last trip - the third week long trip in six years - that we'd have made that sort of time for ice cream (then again, we aren't huge ice cream fans), previous trips didn't leave us two hours with everything else we really wanted to do - in fact, most previous trips we've left things undone that we would have liked to do. We did make it to both B&C and Ghiradelli last trip - B&C because we stayed across the lake at BW and went the day we arrived and Ghiradelli after seeing the first Cirque show, so both times it was convienent - and both times it still took about a half an hour longer to GET ice cream than I expected (a wait to be seated at B&C, a line out the door at Ghiradelli).
