Jim, thanks for your response. Clearly maths is not your strong-point, as even based on your logic, it would be as follows;
"(500-333)*(how much you value their friendship) = Seriously!!!"
I know you're trying to be a wise guy, but it usually helps if you get the basics right. 167 euro is a lot of money to me and my girlfriend, and if the 'convention' is that couples pay less, then I'd clearly opt with convention. So yes, I am 'serious', actually.
Curlysue, thanks, but why would it be 'better' to book a 4-bed? I don't follow your logic at all. First of all, it's more expensive (1200 a week) and secondly, I actually like sleeping beside my girlfriend, so why would we do that? Where I can see some logic in your answer is if we calculate what those two would have paid if it was a 4 bed (300 and 300) and subtract that from 1000, and my girlfriend and I pay the 400. That would make sense alright and we would save 100 euro.
My basic point is, I don't see why couples should be subsidising single-people.
I'll probably pay 500 (250 x 2) to save the hassle and avoid a row, but I just wanted to see what people thought. There's no harm in asking about these things. By the way, I've done a bit of research on the net, and it seems it is usual when people are renting a house together, couples pay less if they are sharing a room.
i.e. in a two double-bed apt rented by 3 people, it's unheard of that a couple would pay 66.66% of the rent, and a single person pay 33.33%....so why should it be any different for a holiday rental?
Thanks for the response/effort though, I suppose.
