Hi, we are coming from Australia to join Britannia on 7th August at Southampton. Fly into Gatwick on 4th August and hire car to Southampton. Not knowing a lot about the requirements for cruising, we booked an hotel in Southampton (Leonardo Royal Southampton Grand Harbour) and a Covid-19 Antigen Rapid Test at the Regenerative Clinic, just up the road from the hotel, on the evening of the 6th August. Probably al a bit expensive, but it is a holiday after all
