Park website gives accessibility facts

Q. My 85-year-old mother has always wanted to see the Grand Canyon. I’ve never seen it either, so I’d like to plan for us to make the trip together. My mother is ambulatory but not for long distances. What would be a good location for us? Is there a particular time of year that’s best?

A. The National Park Service has a website devoted to Grand Canyon accessibility at nps.gov/grca/planyourvisit/accessibility.htm. I’d start with that. Your mother would probably be most comfortable in summer. Take a look at the Park Service’s page on weather.

Q. In October I bought two round-trip tickets on Delta for travel between Washington Dulles and St. George, Utah, with one stop in Salt Lake City, in June. Months after the purchase, the airline changed the return itinerary so that the original nonstop from Salt Lake City to Dulles now includes a layover and change of planes in Detroit. Can they do that to me? Is there any recourse other than sacrificing lots of money?

A. You have two options: You can ask for a full refund and buy a new ticket, or you can take the rescheduled flight. You might also be able to persuade Delta to change your flights to more convenient ones by asking nicely. But yes, unfortunately, they can do that to you.

Q. I’ve been afraid to stay at hotels ever since even some expensive ones started getting bedbugs. What can I do to make sure a hotel is bedbug-free and to protect myself from bringing bugs back home with me?

A. The bedbug scare has waned substantially. Also, the better hotels have tackled the problem by bringing in specially trained exterminators. You can check your hotel at bedbugregistry.com.

You can also be a smart guest and follow a few rules: Don’t put your luggage on the bed. Check the small creases in the bed for evidence of bedbugs. Seal your clothes in plastic bags.
