I flew about 60 hours VFR during the R112 period and didn't have a single issue at all. No FPLs rejected, no confusion over the radio and I even had an electrical emergency and Atlas permitted me to fly through the R112 despite a complete electrical failure imminent. The longest I ever had to orbit waiting for permission to enter was about 10 minutes but that was only once, every other time I was inside within a couple of minutes of requesting entry.
Don't see why everyone was so negative about it, was easy.
