OMG
Your "finding Playa" story sound almost like mine! We too found Playadise in the late 80's (1989) on a side trip from Cancun. I have since lost track of how many times I've been back since.
We also live in the Boston area (MetroWest). We've heard of Hopkington ... might have even seen a sign for it once.
BTW ... when is your next trip to PDC? We'll be there again in June.
