Portsmouth · Gunwharf Quays · Same estate
Holiday Inn Express Portsmouth – Gunwharf Quays & Grosvenor Casino Portsmouth Gunwharf Quays
A harbourside estate under the Spinnaker Tower with a hotel above the shops and a 24-hour casino floor.
The Holiday Inn Express stands on The Plaza inside Gunwharf Quays; Grosvenor Casino Portsmouth occupies the Central Square South Building a short walk across the estate, next to Portsmouth Harbour station.
Gunwharf Quays is Portsmouth’s waterfront estate of outlet shops, restaurants and bars, with the Spinnaker Tower rising from it and the harbour ferries alongside. The Holiday Inn Express sits on The Plaza inside the estate, “above designer shops and restaurants” in the estate’s own words, with breakfast included, guests 18 and over, pets at £10 a night and on-site parking at £2 a day.
Grosvenor Casino Portsmouth Gunwharf Quays is in the Central Square South Building, listed by the estate itself. The doors never close; tables deal from 1 pm until 4 am, or 5 am on Fridays and Saturdays, and there is a poker room. The à la carte restaurant runs from 7 pm to 2 am according to the estate’s listing, with live sport on screens and step-free access.
Portsmouth Harbour railway station is beside the estate with direct trains to London Waterloo — the pairing most convenient for a day trip from the capital.
