We all love the comforts that a hotel stay offers, such as room service and housekeeping. However, some want to take the experience back with them by keeping a few "souvenirs" from their stay. StarMetro lists some of the common items taken from hotels by guests.
Magazines and books
Usually, a TV guide is placed in the room for the convenience of guests and not for them to take home. However, pencils, notepads and envelopes are complimentary.
Some hotels have a hairdryer attached on the wall of the bathroom while others are available to guests upon request. However, many hairdriers have fallen victim to "accidental" packing by guests. Maybe the hotel hairdryer is more to their liking than their own.
When travelling, we sometimes do not pack our own towels as the hotels will provide us with clean, freshly laundered towels. Little wonder that many guests find them so comfy that they take them along.
Many fall in love with the warmth and comfort bathrobes provide, and want to replicate the experience back home.
