We just spent three months at The Reef. During our stay, dozens of people driving through stopped to ask what sites cost there. They were mostly folks staying at Playa Bonita or Playa del Oro, looking for something less crowded.
The Reef is 3-4 miles from downtown, so it's not for those who want to hit the bars at night, but for those of us who want a quiet beach, huge sites, good 50 amp power, usable Wi-Fi, and only a few neighbors, it's as good as it gets.
If Spring Break weren't about to start, we would still be there. It's a zoo during that time.
