I stayed for one night on my way to Brighton. Being at the end of the runway, it was noisy till almost midnight and from 6am. If you are used to this kind of noise then it might be fine for you. I spoke to a delightful lady who had been staying on a seasonal pitch at Gatwick for 40 years and she said she didn't hear the planes. The wardens mentioned the noise as soon as I arrived and they were helpful and friendly. Perhaps the club website should mention the noise a bit more prominently. I was expecting it but others may not be.
