Yes, those items were released by Disney. They were both only available at the parks. I have both of them. The DVD set has a dvd for each park and the
Disney Cruise line. They are just little souvenir video of the park, they really don't go into much detail about the parks or their rides.
The 2 CD set is great! It has music that can only be heard in the parks. Though it had a lot of stuff that can be found on other park souvenir cds, this one has music from MK, EPCOT, AK and MGM. Songs like the Beauty and the Bees music you hear while waiting to get in the theater at AK's Tough to be a Bug. The music from EPCOT's Soari', Grim, Grinning Ghost from MK HM. And the Tower of Terror music from MGM's TOT.
But I would not buy them from Laughing place, they really jack up the prices on their stuff. I would check out Ebay, Half.com, and
Amazon. And I think both of these are still being sold in the park, so you could give WDW merchandise a call and buy it directly from them.
