I went on August 30th

you have a guide taking you around showing the characters clothes, dressing rooms, green room, the tray where they collected their script etc. Then we walked round sets, you wouldn't believe how small Gail's house really is, then we saw Jack and Vera's house. We were taken into the knicker factory, where we were told they aren't really sewing lol it's fake

next we went into the Rovers, where the guide took a picture of everyone in our own groups taking a picture behind the bar pulling a pint. You don't have to take the picture if you don't want, or you could just take it and not buy it later on in the gift shop.
After this we went to the Bistro, had a look round then the indoor tour was over, now you are free to go tour the outside set and now is the time you're allowed to take pictures, not inside. So we just had a look around and took pics outside the rovers, The Kabin, StreetCars, Roy's Rolls etc.... it was pissing it down so we didn't stay too long but you're free to stay as long as you like. Lastly we went into the hospital set bit which is where the gift shop is, it's okay, could do with more variety though and a bit overpriced, got a nice corrie mug though

all in all it was good. It finishes in less than a month (4th October) they're knocking it down :/ so hurry up if you want too go!
