Here is the info on Mary's site:
30-Day Fun in the Sun Pass
The Fun in the Sun pass, which is not available at the park gates, is good for unlimited admission for 30 consecutive days to the following:
the four major Walt Disney World theme parks
the Disney water parks
Pleasure Island
DisneyQuest
Disney's Wide World of Sports complex (sporting events requiring a separate admission charge are not included)
Kennedy Space Center Visitor Center
Salvador Dali Museum
Edison-Ford Winter Estates
Miami Seaquarium
Everglades Safari Park
The pass also includes one Character Breakfast voucher redeemable at selected Walt Disney World restaurants. Fun in the Sun is a multi-day pass, so it includes access to the Disney transportation system.
The 30-Day Fun in the Sun pass is promoted by Disney only in certain countries, including Germany, The Netherlands and Australia. You can purchase the Fun in the Sun pass at major travel agencies in those countries. I'm told it is not intended for sale in North America, but there are outlets selling it to US and Canadian residents (see below).
This pass is an excellent bargain for those who will be visiting Walt Disney World for longer than a week, since the price is only a little more than the cost of a 7-Day Park Hopper Plus purchased at the theme park gates
