I’ve attended at different times in the past including a Friday evening before closing and never had to wait 3 hours! I’d just go and they should give you an idea of wait time at the door x
I took my toddler with a fever on a sat eve and they said the wait time was 2 hours and it was pretty much that . I got the impression you should sit and wait but you could always check when you get there and ask . I would suggest not delaying if you want to go as on the Sat tea time we went it went into being over capacity ( can’t rem what the proper term was ) but they were turning people away and I believe they only agreed to see us due to my daughter being so young and with such a high fever after they consulted about it .
Sit and wait. Last time I went it was a 6 hour wait, I was 38 weeks pregnant with a toddler in abdominal pain. It was absolutely rammed, I had no where to sit and no one would give me a chair. My toddler was screaming. After 3 hours I just broke down into tears and I miraculously got seen straight away 😂
Usually have to sit and wait, when I’ve had to go in with my daughter they usually tell us to just sit and wait and we’ll be seen shortly xx
