My fiance and I went last May, and we didn't even wear the ears and I didn't even have a ring then, but people asked us all the time if we were on our honeymoon!! It was really funny.
I don't know if you guys are eating at Califorina Grill, but that was one of the most amazing meals we had when we were down there, same with Jiko. The later you make the reservations, the less likely kids will be there, but when we were at Jiko there weren't any kids. (But there are still going to be kids, but it's not as bad!)
We also had fun at Epcot, one of the days we were there was sat down and people watched for an hour, for me that was fun just to watch everyone pass on by in a rush. Another thing is, just relax, go back and have fun at the Hotel, especially during the middle of the day. When you go back later there is less of a crowd.
We also had fun going on Thunder Mountain whille they were doing wishes, there was no line, and we got to see the fireworks at the same time.
Congrats and have fun!:wave:
