No experience with PCA, but I did an overnight at Sterling while bringing my airplane home after purchase in '07. Very nice folks all the way around. Good experience for me. Have a fun trip!
PCA is also a training and rental operation with single engine Cessnas. Also nice people. I usually park in transient parking in front of the hotel just past PCA. If you need a hangar I'd suggest checking rates but I never saw a lot of spare room in them...
Sterling has a great avionics shop, PCA does oxygen refills.
