My brother and sister-in-law were wearing those ears and got all kinds of kindnesses from strangers. One guy walked up and said, we've got two extra seat on our illuminations cruise and we'd like you to join us. He refused to take any money for the kindness. They had a great time.
How about a local baloon sculpture store doing some really nice baloon decorations for thier room, and having them deliverd prior to thier arrival. Balloons are neat because they can be very large.
Come to think of it, heck, how about reserving an illuminations cruise for them one night.
Or, I guess you could always do like my brothers did my wife and I when we went to the Grand Floridian for our honeymoon. They got into our luggage before we left without our knowing about it and took all our underwear out, bras and all.....It was quite a surprise when we arrived to our destination. I think they laughed about that for a long time....
When we arrived home, there was a tent pitched in our living room. They had a blast pulling those things off. We had people dancing on tables at our reception........
Many florist shops carry candy/snack baskets now instead of just flowers. They look great and are more useful, appealing to both genders. You could have those sent to the room, they might come in handy throughout the trip.
