The first time I stayed at the Poly in 2005, the shower pressure was so incredible that I was disappointed with the pressure at the BCV's (we did a split stay that trip). I stayed at the Poly again two years ago and found the shower pressure fine, though not as good as before, though that might have to do with more low-flow shower heads. This past trip, I was at BC and the pressure was good, but not as great as it was that year at the Poly...again, probably due to the shower heads.
Shorter, in all trips, I've never had bad shower pressure. Just some showers have been better than others.
