If you are seeking to tour a facility, I highly suggest you give the local NATCA representative a call and try to set up the appointment with NATCA . . . as opposed to an FAA stooge.

All I have to suggest is to ask as many questions as possible, get a look at the local airspace maps and radar screens, it'll increase your situational awareness of your local area. Have them point out trouble spots, areas of high congestion during arrival and departure pushes. . . these are the areas that you, as a VFR PPL ASEL need to stay away from. Have them point out areas of higher than usual concentration of VFR, primary target only traffic sites. . . so that you, as a VFR PPL ASEL, can provide yourself a higher level of awareness to these areas to keep you from hitting another aircraft.

These are just a couple questions for a smaller Class C location. I'll give you more if you manage to get into a larger TRACON environment, or even an enroute facility. Enjoy it and above all else, tell each and everyone of them thanks. Controllers do a job that not many people are able to do, they deserve respect, as well as a fair wage and fair contract. Let them know you are on their side as a General Aviation pilot. GA is the National Airspace Systems largest user, and controllers and GA aviators are each others greatest ally.
