We are spending our Honeymoon at Disney from Sat. Aug. 25 to Mon. Sept. 3 at the POFQ

. Since we booked the
free dining package we will have the opportunity to eat at a lot of table-service places.
Anyway, because of reservations, it looks like most of our trip will be governed by where and when we are eating. Multiple times we will be going from one park straight to another or from our hotel to a restaurant in another resort.
One example we have planned is AK in the morning for EMH then to MK for a late lunch. Is bus the best way?
A more interesting example is the night we arrive. Our flight is supposed to land at MCO at 5 p.m. then we are taking the Magical Express to POFQ. After settling we want to go to DTD for some shopping then we have a 9:15 p.m reservation at O'hana. Is this time-table even possible, and, if so, what is the best route to take?
I'm running into trouble getting from DTD to Poly (ferry from POFQ to DTD seems best for the first leg). Is there a bus straight there or would taking a bus to MK then monorail to Poly work best? (FYI: That night is EMH for MK so they are open until midnight: we shouldn't have to worry about transportation stranding us at O'hana).
Sorry for the long-winded-ness.
