When you get a Lancaster permit, it will not be considered a renewal. It doesn't really matter, though. If you mention that you already have another PA non-res, they'll gladly point out that you're not renewing that permit, because you're considered a new applicant.
I was just in Lancaster this afternoon. 30 was packed, probably with gift-card-laden shoppers enjoying 60+ degree weather. When you go to the courthouse, though, you're biggest problem is just finding a parking space. You can do on-street, but you'll never know how long that you will be there. When I was there earlier this year, I parked in a garage about two blocks before the courthouse.
