I spoke with Izzy on the phone yesterday, she did mention that only 2 others had been in contact about the ferry.
It would appear from our conversation and the message board that there are about 10 of us needing the ferry.
From our conversation I think they have an issue with email to info@dalileafarm.co.uk going into a spam/junk folder, as I received a reply today.
Izzy confirmed we would need to give them a call the week before the challenge. The phone number is 01967 431253.

Thanks Darren, Sounds like lots of different messages around so we'll try and coordinate nearer the time. Regards Al
