They usually believe you. You've read right, hotels are favorite places to make love. No matter if you bring your IRC date here, pick up a hooker or stay alone and watch the in-house porn movies. Since many hotels pride themselves in having as much staff as guests, the question is how to get the cute waitresses and maids into your bed. If anyone has experience making them willing without much financial and physical effort, drop me a mail and I will include it in the next list.
Some people love to take all movable parts from the room before checking out.
The question is what to take and what not. The easiest things to take are soaps, shampoo, lotions and Kleenex from the bathroom, since they will be replaced every morning without problems. They will bring you a new one immediately. If you want a bath towel, also don't wait until the end of your stay, but hide it some days earlier. If anyone should ask about it, just tell him that you left it at the pool.
