How exciting! You will have a wonderful time, and POR is a great place to stay. Your question is very big and it would take a book to answer it completely, so let me just make a few comments. Epcot will be a great spot during your adults only trip. Flower and Garden will be going on with its food kiosks, concerts, and pretty displays. I would spend a little extra time here taking it all in. I also enjoy taking advantage of the boat to Disney Springs (Downtown Disney) from POR. We love to eat a Raglan Road and enjoy the music and dancing along with the good food. Let yourself be a kid again at Magic Kingdom: meet characters, ride old favorites, check out the new Fantasyland including enchanted Tales with Belle if only to check out the amazing detail and theming, have a Dole Whip, and enjoy the new afternoon parade. At Animal Kingdom enjoy the shows and don't skip the Nemo musical thinking it is a kid's puppet show. It is a fabulous show! I'll leave the rest for others to comment on, but I hope you have a great trip!
