Hmmm I'm in a bit of a situation here. Had a visit booked at prestwick but it has been cancelled due to manning shortages. With such a short time until my final interview and no scope for any extra time off work, I am worried this will have a negative impact on the 'preparation' side of my interview. I currently work in a RAF control tower, and have visited 3 others, but no area centre. Any advice? Is an ACC visit a must?
