Only the ground floor space in the terminal building is used for passengers. Upstairs there are offices and the Douglas Harbour Control Unit. In the main departure lounge, there is a
Costa Coffee café,
WHSmith store, a Steam Packet ferry travel shop, a play area for children, toilet facilities, foot passenger check in area and a model of the
Laxey Wheel. Outside the main departure lounge, there is the arrivals hall with baggage belt and the Isle of Man Welcome Centre. At one point, there was a restaurant on the top floor called the Crow's Nest. This is now used as the harbour control unit. The restaurant was quite popular, as it gave views over the main harbour. Next to the terminal is the vehicle check-in and marshalling area, where all vehicles must wait until the ship is ready for boarding. The Sea Terminal was formerly used as a waiting point for passengers travelling on the Laxey Towing Company's
Karina pleasure cruiser. It operated daily trips to Port Soderick, Laxey and other destinations from the cruise ship landing stage in the harbour next to the Victoria Pier. ==Connecting island transport==
