We didn't get any upgrades, but Port Orleans (FQ) gave us an amazing gift basket - with all kinds of goodies. Wilderness Lodge sent a bottle of champagne and a fruit basket to our room.
Make sure and mention it when you check in/make reservations or check in to restaurants - it doesn't guarantee anything, but most cm's will try to spread a little extra pixie dust for disneymooners.
Congratulations on your overdue trip!
