I was drawn to the Disney Rewards Visa by Chase because I am a Disney freak. I couldn't resist the cute Disney designs (the you can call to change whenever you want)! I also love that all the purchases go toward Disney Reward Dollars that you can use at Disney Stores, disneyshopping.com, Disney Parks, towards Disney movies, products, etc.
There are also additional perks and offers for being a cardholder. I often receive emails with special deals on Disney travel and products before they are released to the public. Also, on my recent trip to Walt Disney World, I checked out my perks before I went. I could have saved money at the World of Disney Store in Downtown Disney, but we did not make it there. We did do the special character meet & greet at EPCOT and took home a great souvenir photo with Mickey and Pluto (5x7 included as a perk!). I think there is 0% interest for 6 months on booking Disney vacations directly through Disney.
I don't think there is anything special as far as interest rates go. As for the rewards, you only earn 1% (so you basically get 1 Disney Dollar for every 100 charged on your card). You could really play up the system but I am a little more conservative so I do not earn as many Disney dollars as I would like.
I think it is fun to have as a Disney fan, and I am proud to carry the Disney Rewards Visa.
