I have just been on, and checked out rates for 2 nights (16th & 17th).
I can get triple rooms for £55 per night, works out at £36 per person for 2 nights.
I can book them right now, only problem is I have to pay upfront, but that would mean I'd need the money from everyone pretty quick (the total bill was something like £444, so don't want to book them till I know for sure who want them!)
Dilema!
