Unfortunately I booked the night qualification and a ten hour block on the PA38.
Only completed 55 minutes of the night qualification due to weather.
You need to pay for a 10 hour block for the £85 rate and I have only used one hour and a bit.
I understand why people recommend pay-as-you-go unfortunately the discounts are too tempting for myself.
If this post turns out to be true, I will NEVER pay upfront ever again even if it costs more in the long run.
