Rock star and TV talent judge Steven Tyler was recently severely injured when he slipped and fell in his Paraguay hotel shower. Astronaut John Glenn and other people have had similar accidents. It should be a warning to all travelers. Many hotel shower stalls have slanted floors and can get very slippery when soapy.

Additionally, outside the shower, the bathroom floors are often made of very slippery marble blocks. It often happens that the more upscale hotels have the the most dangerously slippery shower stalls and bathroom floors.

If you’re elderly or otherwise unsteady on your feet, when you check in to a hotel, ask for a handicapped room. They usually have elbow-high bars on shower stall inside walls.

As if we aren’t fed up enough with the increasingly annoying ads flashing on TV and computer screens. Next time you fly you may find yourself surrounded by equally bothersome poster ads tacked onto every inappropriate inch of your airplane.

Spirit Airlines, Ryan Air and others are raking in millions of dollars from sponsors by displaying ads. Passengers will not only see the big ads, but also little ones on tray tables, barf bags, flight attendant aprons and every other space they can think of.

Q: We haven’t been to Las Vegas in a couple of years, and want to book a visit for next month. We’ve been warned to stay at a hotel that does not charge resort fees. What are resort fees?

Jay S., Providence RI

A: It’s a hidden extra charge, similar to what airlines do to lure customers. For example, when you book a round-trip flight advertised for $99, the real amount you pay may be $120 or more, because of fuel fees, taxes and other add-ons.
