We've booked accommodation (thru homeaway.co.uk) for #OggCamp 2019. It's a few miles outside of Manchester, but we've booked parking (thru justpark.com) so that we don't have to pay for the 5 of us to take the train or taxi into the city.
Never tried crowdparking or crowdlodging before but, if the experience is positive, in can see us using this regularly. Save us a fortune!
