I have two favorites! My first is walking around the World Showcase. It's my favorite part of Disney World, it's really gorgeous back there. I know it's not "real culture", but until I can get out there to these actual countries it'll have to do! I love meeting and talking to the CMs from around the world, getting snacks from the counter service restaurants, shopping and buying one souvenir from each country, seeing the shows and attractions, and just taking in the atmosphere. I love it!
My second favorite is spending time at the Polynesian, my absolute favorite resort. I love to walk around and explore the resort before hanging out and relaxing by the fountain and garden in the lobby, just listening to the water and smelling the coconut and tropical flowers. Then we usually go for dinner at the Kona Cafe, one of my favorite Disney restaurants!, before sitting in the upstairs lounge and listening to the performers play the guitar and sing classes Jimmy Buffett and Eagles songs. Then we head out to the beach and pull up some lounge chairs and settle in for the night, watching the small waves crash on the beach and listening to the soft caribbean music before watching the Electric Water Pageant and Wishes! Now THAT'S magic!!
