HRH lot is small and fills up. If the HRH lot is full, you could park in the PBH parking garage, which is covered and doesn't have the ant problem. Then take the shuttle bus back to the HRH. If I was staying at the HRH and driving my own car, I'd park it in the garage at the PBH because they have a ton of spaces. I'm surprised the HRH hasn't caught on to this idea yet.
For the RPR, we checked in, then parked our car in the grass along the road that goes around the hotel. We went in thru the side door and it was close to our room.
