I spent yesterday afternoon doing the gingerbread/decoration thing. We parked at yacht club saw there, and walked over to beachclub and back. We skipped boardwalk. Then we drove over to GF and did there, monorail to contemporary, boat to wilderness lodge, boat to MK, monorail to poly for dole whips and fireworks then walked over to the car at GF.
We would have added dinner but we did a afternoon holiday meal for xmas before we started our adventure and weren't really hungry and the dole whips took the edge off. It sounds like a lot of waiting for things but it was a great time to just relax, enjoy not being in the parks and taking in the holiday for us.
To be honest, as adults enjoying your time together you can't really go wrong picking any specific place to start a peaceful journey that is more than a meal somewhere around property. Now if there is somethign more specific like dancing or music then there is less locations to aim for in the adventure.
some hint in what you want/like other than no theme parks would be helpful.
