You might have already gone if yesterday but I was going to say about 20-25 mins though need to factor in some disruption as there works being done to put in another line in the city. It affects other lines mainly but there can be a knock on. Always best to keep an eye ahead as issues such as faults, broken down trams or accidents (some lines run on roads and pedestrian areas) as one issue can have a big knock on effect.
If you do get there early then there is a Costa coffee, Booths Café, deli and some other places where you could pop for a coffee if early. They are not immediately visible from the tram stop but just head between the big studio buildings. You will be able to get a glimpse of the outside of Corrie's new home too.
