Yep, no villas at YC. The Yacht Club and Beach Club are two separate resorts. Right smack next to each other, and they share recreational facilities, but they are not one big resort.
Actually, there's three resorts there. The Yacht Club, the Beach Club, and Beach Club Villas. All three are operationally separate, and you would select one of those three to book your lodging. YC has standard rooms, club level rooms, and club level suites. BC has the same. BCV has studios and one and two bedroom villas.
