Airport Hotels
If you are SYD Based Crew you are a long way from home in LHR.Airports generally have nothing around them.No retail shops(except duty free) no supermarkets,no gyms or bookstores.Nothing to do.Boredom even for 38 hrs.London is not Heathrow Airport.A tragedy in Architecture and design if ever there was one.
The issue is fairly self explanatory.
As jettlager says..it aint happening anyway.
