Andy - I'm going up early as usual but really sorry to hear this - I hope you manage to get something sorted out and I see you there.
Something else re ferries that not everyone might know - Port Ellen pier is out of use this year, it shouldn't affect too many people as most go direct to Port Askaig but if anyones planning a few days on Islay first it makes a difference - the good news is that as far as I can tell the Sunday morning ferry that normally leaves Port Ellen is now going from Port Askaig, so anyone wanting an early return on the Sunday will find it easier than getting up very early and riding like mad down the length of Islay.
