Hi Kimberly!
The Walt Disney World Swan and Dolphin hotels are located in the heart of Walt Disney World, between Epcot and Disney's Hollywood Studios, but they are independent hotels and not owned or operated by Disney. Since they are not owned or operated by Disney, you can not purchase a Disney Dining Plan while staying there.
You can wait until you get to Walt Disney World to buy theme park tickets or you could
buy tickets online. Another option is to pick them up at a local AAA office if you are a member.
The Swan and Dolphin are very nice hotels. I've stayed there a couple of times myself. They have a great pool area. Guests get access to Extra Magic Hours and have Disney transportation to the various theme parks, water parks, and Downtown Disney.
I hope this helps! Write back if you have any more questions!
