I agree with NancyK, take the time to resort hop, maybe stop for a drink or a snack and enjoy the surroundings. A big "must" for me is Afternoon Tea at the Grand Floridian, served between 2 ~ 6 o'clock, you don't have to make a reservation unless you are a large group. We also like to take the various boat trips ~ those in the Magic Kingdom resort area, the Boardwalk resort area to EPCOT and MGM and from DTD to Port Orleans Riverside Resort along the Sassagoula River. Very relaxing and you can stop and look around the resorts, including Fort Wilderness Campground. If you're taking a Saturday off from the parks, go over to the Poly and sit in a hammock on the beach under the stars and watch the Fireworks from MK. (I checked the schedule and unfortunately Saturday is the only night for MK Fireworks in October but that could change so be sure to check when there.)
Since you will be there for 2 weeks, you will have lots of time to enjoy the things you discover and possibly have time do again and my best advice is to relax and have a wonderful time!
