Annie - thats so cool I looked at that tour too but it didn't link up with what I wanted to do. You will have to let me know what Belfast is like (I am desperate to get there) and make sure you get to the Guinness Storehouse in Dublin and if you're a history buff kilmainham gaol - it was one of the highlights when I went to Dublin, and Dublin is probably up there with my favourite places in Europe.
Stefanie - will you be in Edinburgh for Hogmanay? Because I will be too but on a different tour just for New Years!
Are you all staying at the Fron? I was told that was most likely where the tour hotel would be. Looks nice.
I'm staying an extra night as well but I'm flying Icelandic Air - they had a direct flight from Munich and to London which worked out cheaper for me. Sometimes its cheaper to buy a return ticket in Europe than a one way.
