We rented the entire compound for the group of us and it was an incredible launching pad to get everywhere on the island. It was pretty much a 30-45 minute drive to some incredible beaches and coves for snorkeling and surfing. The house is equipped with everything that 12 young adults would need - including a projector and Apple TV, speakers, and equipment for a fun day at the beach.
During our stay, we used one of the homes to do group dinners for our entire home and found it to be more than accommodating for the entire group while balancing the privacy and need for downtime for different members of the group. The fact that the street is in a gated compound made people feel safer. Finally, Dan was super responsive with questions I had around logistics.
If you're going to the Big Island with a big group, I would recommend checking out the Kumu Compound!
