Not beachfront but overlooking the Royal St. Kitts Golf course and just a 5 to 7 minute walk from either the Caribbean and Atlantic side beaches at Frigate Bay try: Calpso Bay Resort (actually rental condos), Silver Reef Condos and Sugar Bay Villas. Also, have you checked Timothy Beach Resort, many of their rooms & Suites kitchenettes and king size beds. For what it is worth - there are well over 200 rental condos/villas in the Frigate Bay area - I'm sure many have king size beds - check websites like VRBO, AirBnB, Homeaway for listings. Anything in the Frigate Bay area will be either beach front, beach access or just a few minute walk to the beach.
