If you're considering taking a pram it'll be a nightmare. I go every year and always think 'why would anyone bring a baby here?' The Glasgow one in the SECC is always incredibly busy and some of the stands are quite close together with not a lot of room to manoeuvre, and the seating areas are always jam packed. People usually end up sitting on the floor with their lunches.
No that's great thanks it's the Glasgow one I was considering. I went to two thi ga close together at the secc while pregnant and remembering thinking one of them would have been a nightmare, now I know which!
