We have complete down days and we also leave a park around noon or alittle later and head back to the resort for a dip, lunch, drinks or nap. We're late 50's, children grown and gone, headed for our 40th trip in January, always stay deluxe, have AP's and stay no less then 9 nights. We enjoy all aspects of WDW, not just the parks but when we do the parks, with AP's we can pop in, see what we want, shop alittle, grab a favorite snack and head out. We picnic/party at our pool. Room rest to cool off more and maybe nap. We don't head back out till around 5 or 6, and most always to a different park. We like to catch each park for am hours and each parks for evening time to see it all. Ain't nothing popping over to EPCOT just for Illuminations and stopping at another resort for a lounge tour.
During our stay we do have a complete down day, that is no park, we might spend whole day at resort, pool, or pop over to DTD to get the shopping out of the way, usually end up at FW though, for beer and pizza, we most always are staying at WL and its a nice boat over and back and sometimes stop in at CR.
We use to go, go, go all the time when we were younger, had the kids and didn't stay very long. Taking the kids, runs the ticket price up plus food bill hence the shorter stays. Now just wife and I, stays are alot longer, its food and tickets times 2 and we have seen and done everything but like our favorites so we spend considerable time in the MK, again why we prefer WL, alittle time in MGM, bit more time than MGM in EPCOT and rarely go to AK. By taking WDW in little bites, enjoying the resort which we paid good money for, visiting other resort lounges that have nightly entertainment, and lounging for a few hours at our pool make Disney the ultimate place to vacation for us.
