Of coarse you should go. The walk from the HRH to the PBH is only 8 minutes. Go at night and you'll get to see people singing Italian songs on balconies. In the morning, everyone sits outside in front of a cafe reading newspapers and drinking coffee.
The RPR has the largest pool in Orlando, or it may even be Florida, worth seeing. You can use all the pools, so bring a change of cloths and go swimming if you want.
