I've just worked out that given that to block book the whole hostel for 2 days costs £750, at a normal cost of £12 per person per night we would need 32 people (staying 2 nights each) for us to break even, anything more than that and we have a surplus. The hostel can hold up to 50. At such relatively short notice there were 18 booked in, with more time to plan (& save pennies) do we think we could get 32 or more to make it worth booking the whole place?
