Luxury hotels are increasingly offering sleep menus. No, this is not being fed through the ears while you sleep, it is offers of services and amenities to help sleep come about easier.
Sleep menus often include:
Aromatherapy, such as baths or candles
Scented (usually lavender) eye pillows
Even the most sacred of sleep-inducers is available…teddy bears. Though, knowing that the bears sleep around with every Tom, Dick and Jane, may induce a long wakeful string of imaginative pictures while you cuddle it, instead of sleep.
