My heart is bleeding when I see you sissies crying ;o)
The thing is that we could rent a 10 person tent (I mean extra one, as we're already taking one for us). There are 2 problems however - one is our coach's cargo space (I believe we could fit it in somehow though), and the second is the price - 100 EUR.
If you are willing to chip in for something like that, let me know until friday.
