Parents who have visited theme parks with their kids know that riding the rides (even the scary ones) is the easy part. The greater difficulty comes from having to run the gift shop gauntlet at the end of the attraction before you can see daylight. It takes an act of parental super-restraint to get your family through all the tchotchkes without opening your wallet. Our boys are all teens now, but memories of such navigation at Disney and Universal are not soon forgotten.
So I get that some had concerns upon hearing there is a gift store at the National September 11 Memorial Museum. Having visited, I can report that it is nothing like the entertainment equivalent. More.
