Cap Ducal

Cap Ducal is the ship-shaped building on Avenida La Marina, set on the rocks above the sea between the Sheraton Miramar and the casino. It runs as a hotel with a restaurant, and Google rates it 4.4 from about 1,200 reviews. Rooms are older than the chain hotels nearby, so book it for the setting rather than for luxury. It's a mainstream hotel, not a gay venue. Chilean law has allowed same-sex marriage since 2022 and bans discrimination by sexual orientation, so couples book a double room without fuss.
