We reserved both Breakthrough and Bodhi Tree together due to our group size, and it worked out perfectly. The sites were close enough to feel like we were together and have meals together but separated enough to give a little privacy. The tents were spacious and comfortable, and there was enough open space that those who wanted to cowboy camp under the stars had room to do so. Although people usually complain about port-o-potties, the one shared by these two sites was spotless and well stocked with toilet paper.
The camp host was superb. He came back multiple times to make sure we had everything we needed, to give us a description of where we could walk, to lend us items that we forgot to pack. He even offered to guide in a late-arriving guest so they would not get lost in the dark.
The kids loved the campsite dogs who came to protect us and hang out. They, and the neighboring dogs had much to bark about at night, so pack your earplugs. But we did feel safe with them around.
As far as driving, it can be done with a regular car, though on a rainy day I would only want to try it with an all-wheel-drive with some clearance. We had a dry day. The GPS gets close. The host sent us a message to wait at a particular sign so they could guide us to the site, but we missed that sign and drove in ourselves. The last part was a bit confusing. Most of us made it directly, but a couple guests got lost. If you can, read the signs well and contact the host for help.
It was a great stay!
