On arrival day we eat at Chef Mickey's (subject to change since I'm about over paying $80-$130 for ONE MEAL) and then head back to our resort to swim, unpack, and just get a lay of the land.
Our first and last full days are spent at MK. I don't know, something about MK is just so Disney to me and I love to start and end our Disney vacation with a trip to MK. It's also nice to break our MK time into 2 days, as we can then enjoy a nice character or sit down meal during the afternoon parade (off peak often means lower prices) and then just hit up the parade on our 2nd day there. Same goes for Wishes. Then we don't necessarily have to stress if we miss it one night. We know we can just see it the next night we're there.
We also plan one full day to enjoy our resort. Last time we stayed at POR and we could have easily spent 2 or 3 days just enjoying the resort. The pools, the restaurants, the boat to DTD, carriage rides, all so fun.
