If there are info booths already in the park, if you find the panel with the list of rides, and there should be an option for shops and facilities. Any existing booth would be under shops and facilities. When you select them there will be an option to centre on the building with camera, in the window it opens for the facily or if you select I think it takes you there. (Can't remember the exact windows on console). If you have yet to place them, when you go to build shops, there should be an information icon to filter by I think.
