We normally don't move our car either. We usually stay 4 or 5 nights, & have actually used our van twice in all our stays. One was to make an emergency trip to Walgreens. The other was on our last visit, & we arrived later than planned. By the time we checked in & took our luggage to our room, we didn't have time to walk or transfer boats to PBH for our dinner reservation. This particular time, we drove to PBH. We usually don't. Every time we've been there, the gate has been up though. That said, If it were us possible, we'd take the boat to CW & transfer to the PBH boat, as t-and-a suggested.
FYI, there's lots of parking near the entrance to the Convention Center at RPR. If you ever have a hard time finding a place to park, continue past the 1st lots. You'll find plenty of empty spaces around to the side. On the other hand, HRH definitely has parking issues.
