For me, it is Amber Velours from Givenchy. It is exclusive to Disney in North American. Spicy and incense-y, it's really great.
I also really like some of the Guerlain perfumes that are pretty much exclusive to the Guerlain boutiques and Disney. I bought Cuir Beluga and and Tonka Imperial. Totally amazing perfumes, and work really well together. I also bought a version of Miss Dior perfume there and got the bottle etched with my name in the France Pavilion. Perfume shopping in Disney is a guilty pleasure for me.
I started really enjoying and exploring perfumes this year.
