Hi Andrea,
PhotoPass Plus is a great option if you love getting attraction photos and character dining photos. The participating attractions are Space Mountain, Splash Mountain, Buzz Lightyear's Space Ranger Spin, The Twilight Zone Tower of Terror, Rock 'n Roller Coaster, Expedition Everest, and Dinosaur. I think the only attraction that you will most likely go on with your kids will be Buzz Lightyear! The Participating Character Dining Locations are 1900 Park Fare at the Grand Floridian, Ohana (breakfast only), Spirit of Aloha Dinner Show, Chef Mickey's, Cinderella's Royal Table, Tusker House Restaurant (breakfast only), Hoop Dee Do Musical Revue, and the Princess Storybook Dining at Akershus Royal Banquet Hall in Epcot. The PhotoPass Plus includes Print Packages at the above dining locations, digital downloads of the attraction, a special PhotoPass Plus card and Lanyard, a gallery CD with over 400 photos of Walt Disney World, and a unique code to order a PhotoCD with all your photos online. I would recommend this if you are going to be dining at the above restaurants, otherwise, I think you will be fine with the regular PhotoPass. I just know your trip in February will be just magical, Andrea!
