10 Secrets Hotel Owners Don't Want You to Know

1. At most hotels, only the sheets are changed every day. The blankets may be washed weekly and the bed covers are lucky to see soap and water monthly. If you want everything to be clean, you have to ask.

2. Most hotels aren't liable for what happens to your car at the hands of a valet. Hand over the keys at your own risk.

3. Television remotes crawling with rhinovirus, a germ that can cause the common cold, and are rarely cleaned by staff.

4. Hotel pools are highly chlorinated, which kills most bacteria. We can't say the same for the tables and lounge chairs, however.

5. Hotels pay online booking agents up to 30% commission (and guess who picks up the tab?). If you really want to save money, call the hotel to book your room and politely ask if there's any way to reduce the rate. You might be surprised at their flexibility.

6. Always wash the glasses by hand before using.

7. Housekeepers have a lot of rooms to clean. If you rush them by checking in early, there's no telling how clean your room may be.

8. Most front desk personnel will waive movie fees, but wait until check-out to ask.

9. Yes, some local establishments will pay a concierge to send guests their way. However, a good concierge knows his or her reputation is on the line with each recommendation, so they're unlikely to lead you astray.

10. If you suddenly need to cancel and want to avoid the fee just call the hotel and move your reservation into the future by a week or two. Then call back the next day and cancel it without penalty.
