I would be careful, if I remember from last year the cleaners may report it and you can be stung for breach of fire safetly, which is a £50 battles charge, as mini-fridges are apparently a fire hazard.
Well ive got some creams that I sometimes use for medical reasons. Hopefully they will allow me to take one. Im pretty sure medical creams have to be kept cool. Only annoying thing is going to be trying to obtain a medical certificate. Plus I really want a mini fridge it will really come in handy.
