As concerned seniors, we have a very basic worry about foreign toilets. When the need for a bathroom happens while on a city street, what do we do? Mrs. PRL, St. Louis MO

A: Before you stroll, be sure you have some of that country’s coins on you for available coin-operated toilets. Use your smartphone to get into apps, such as Flush. It’s free with a map locating nearest public toilets. Also, Freepee.org lists free public toilets in many world cities. Another basic tip: Carry a small soap bar or tube along with disposable tissues.

Q: I’m a retired teacher and want to travel by myself. It gives me total independence and freedom to set my own pace. I’ve gone with groups, but gave up due to restrictive schedules, boring companions and other bothers. What’s your opinion on a single, 67-year-old senior woman seeing the world by myself? Ms MML, Boston MA

A: We strongly suggest you travel with at least one healthy companion. This is necessary where current conditions may be dangerous. While planning, search online for crime rates, political unrest and other reasons to be cautious or stay away.

When checking in, ask the hotel host about current safety conditions. When in public, especially crowded areas, keep your purse safe under an elbow with shoulder strap. Secure phone or camera, and wrap the straps around a wrist. Obey safety rules, and keep your companion close at all times.

During my work career, I did a lot of business travel and always used an agency. Now, as a retiree and with all the available online resources, I’m considering doing all the research and booking myself. Opinion? LJMcC, PhilaPA

A: Of course, you may be able do it yourself. However, if you still travel frequently, remember how your hometown agent helped when you were stuck in the airport because an airline booted you off a flight. Or when you arrived at a hotel and your booked room wasn’t available. Agents are involved daily with the constantly-changing realities of travel, and are available by phone or email 24-7 to help when you need them.

I recently bought an online deal for a Vegas hotel of $120 a night. But when I checked in, the clerk said because I was a senior, I could’ve paid just $99. Are those sites giving out wrong info to make money? MCJ, Atlanta GA

A: Of course online agencies exist to earn money. Sometimes their prices are lower than booking direct with hotels. It’s a matter of timing, season, special promotions and other ever-changing factors. When checking in, always ask the clerk if that’s the best price. Of course, also mention you're a senior, frequent visitor and/or other positive fact. Chances are, you’ll get a lower price and/or other benefits, such as larger rooms, free meals and entertainment.
