Norwich City have had a successful hotel at Carrow Road for the last 7 years. It opened as part of their redeveloped Jarrold Stand.
There's a lot more to do in Liverpool than there is Norwich. There's clearly a demand for hotels. A hotel attached to a historic Premier League football clubs' magnificent redeveloped stadium would be a draw. There's at least one major match, often 2, played in the area for 38 weeks of the year, and that's before business conferences and basic tourism for the city is factored in.
You need to have a vision. It's the whole point behind regeneration projects - taking an area and transforming it.
