If you are stopping at the travelodge and you want to take your meals at the Arrow Mill then you have to print off and fill in that part of the booking form. Hold On, I'll try and find it for you. Then you have to send it off to the address it says and pay as well. I haven't gotten around to doing that bit yet but I will. I don't think I'm booking breakfast even though I can vouch for it's superbness.

This link may or may not work. It's the Non residents meal booking form just so's you know anyway.
