I found that when on circuit’s at Liverpool the instructors at Ravenair would ask ATC beforehand the likelihood of IFR traffic & if any others students / schools are booked into the circuit. ATC would not let too many enter the circuit & none at all if they were to have a busy period with IFR traffic. So if busy we would just tumble over to Hawarden, within 10mins away & do them there, nice long tarmac runway & an odd hold for the guppy. At the same time you get some good practice on RT & exiting / re-entering the zone. So no time wasted in my opinion, whoever you chose to learn with i think you will find Liverpool is a great airport, I absolutely loved training there.
