Thanks all, we managed it without any major problems, even managed an afternoon in Stoke-On-Trent taking the kids swimming, mooring outside the Carvery before tackling the Harecastle tunnel first thing the next morning. All in all a very enjoyable weeks cruise, the only downside was we couldn't go on the Anderton boat lift as the hire company wouldn't allow it on this occasion although they have said if we pre-book it with them they'll be happy to include it next time round.
