The Current (17/05/2011) exchange rates gives us a room price per night as follows:
Single @ 50 euros per night = £43.63 per night
Standard Double @ 72 euros per night = £62.82 per night
Comfort Double @ 82 euros per night = £71.55 per night
Triple @ 108 euros per night = £94.23 per night
So for instance, those staying in a standard double for three nights (fri/sat/sun) , will pay roughly £189.00 for your stay.
Don't forget, if you are paying up in advance to deduct the deposit you have already paid.
£35.00 in all cases except for Clive @ £70.00 (Tim fooked up when paying his
