It's not at all a stupid question!
I don't believe there's a Guest Relations location at the TTC. There is one at the entrance to all 4 theme parks. At the Animal Kingdom and the Disney-MGM Studios, it's to the left of the entrance turnstiles. At the Magic Kingdom and Epcot, it's to the right of the entrance turnstiles.
There's 3 additional locations. One of them is at the International Gateway entrance behind World Showcase. (Convenient if you're staying at the Swan, Dolphin, Boardwalk, Yacht Club or Beach Club). There are 2 locations at Downtown Disney. One at the Marketplace between Eurospain and Team Mickey. The other is on the West Side next to Wetzel's Pretzels.
