We arrived at the NEC in Birmingham for the BIg Bang Fair at 10am - it then took the marshalls until 11.05 to park the coach, it then took us another 20 mins to get in the building. When we left at 2pm, they made us queue up to get outside like cattle. We waited half an hour before escaping through a fire exit and ringing our coach driver directly. We walked up to the first drop off point - had we not, I dread to think how long it would have taken us to get out. Put a dampener on the whole day. Never again.
