In notoriously expensive Switzerland, finding a decent deal on a hotel is hard. However, thanks to the imminent threat of nuclear catastrophe you and 56 friends can stay in a disused bomb shelter for just £17 a night.
None of the rooms have views, there is only limited hot water, no room service, no TV and guests are warned to be expected to share with soldiers, firemen and emergency workers if nuclear war breaks out.
Even if there are no dressing gowns to steal, at least you'll be safe.
