Welcome Home! And Welcome to the DIS DVC Boards. There are some dining discounts (mostly 10%) that vary by time and location. Free valet parking at DVC resorts. The ability to visit other resort pools (not at AKL or Beach Club), it also has black out dates. You'll receive a current perk list when you check-in at a DVC resort on points. Perks are subject to change, and they do change a little throughout the year, but most major changes take place annually, on the first of the year.
Another "Welcome Home"! In addition to what Chuck stated, on the DVC Member site you will also see what wonderful member info you will be available to members - you will receive a mailing with a Club ID and pin to access this site. There's lots of information at your fingertips at that site. And here on the DIS, you can find out a lot of info - just keep reading this forum.
You get a 20% discount on selected services at the Spa at SSR, and 10% off at other spas and health clubs. There's also a 10% discount (on selected items) at Disney Shopping.
Once you get into the DVC Members website you'll see all the discounts available.
