I've met far too many soap stars to name them all, at least one main cast member from Corrie, Emmerdale, EastEnders, Neighbours and Home and Away.
Corrie, I used to go to Quay Street a lot and have only had one successful visit to Media City, as well as meeting cast at other stuff as well.
Emmerdale, I had been to the old studios a couple of times, you could easily meet around twenty in a day if you were there the whole day, it was so easy to meet them. The set-up of the new studios put me off a bit and I now attend Emmerdale events instead of going to the studios.
EastEnders, I've met quite a few past and current cast by visiting stage doors at the theatre. I've only been to Elstree once, in 2013, and met six cast (only one of them still in the show lol) and one of the extras. The set-up there would put me off as well as it's in a residential area and some of them can be a bit "funny", plus you are more likely to meet cast who are on foot as they aren't supposed to stop in their cars, although one or two do.
As I say, I've also done the theatres a lot as well. Chris Chittell from Emmerdale is easily one of the nicest soap actors, always a pleasure to chat to. One particular person who was in EastEnders shall remain nameless, I met them a few years ago and while they posed for a photo with me, they were otherwise very rude and uninterested.....
