We are going to Ireland (also to the North Ireland where we will be accomodate all the time).
Now we have:
2 guide-books (the third was refused for being duplicite)
1 book about Celtic myths.
Seeing that we will be laying in our beds in our accomodation and reading about beautiful Ireland and his landmarks-you-must-see for all the week. I guess the car reservation was very expensive stupidity.
A little bit unfair thing: a lot of people lend us the maps and the guides and a say our trip is enviable. When I went to Russia last year no one lent me anything and all the people though I'm a fool.
