Ok people looks like i hopefully have managed to get rid of the ticket for AllanD who can"t make it.
This leaves 2 nights accomodation at the harcourt hotel
http://www.harcourthotel.ie/ price for 2 nights is 185 euro (again open to negotiation as you would be sharing with me
)
I would suggest that anyone who is booked into one of the hostels (i stayed at the Jacobs last year and will certainly never try that again) to consider this as it will make your weekend far more comfortable/enjoyable...
