Are you old enough to remember Jeeves, the super-competent, snooty butler of P.G. Wodehouse stories and movies? A new service is available for travelers at SFO, and for a fee, an all-knowing Jeeves-like butler can help them with all requirements related to flight schedules and other needs.

Called Airport Butler, the services include personal security, fast check-in, airport escort and ground transportation. They can also be helpful to passengers in wheelchairs and with other physical challenges. www.airportbutler.com

Senior Travel Correspondent CJF, Detroit MI: Everyone says Paris is the most expensive tourist city in the world. To experience April in Paris, we challenged ourselves on a recent visit to do everything possible to enjoy at least one frugal senior day in the famed City of Lights.

Sleep on the cheap: It costs up to $1,200 a night at the super-upscale Paris Ritz, and not much less for other snobbish Paris hotels. So we trekked over to the Woodstock Hostel in busy Montmartre. The charge was about $40, sheets and towels $5 extra.

It’s full of young backpackers and without much privacy, but there’s a little swimming pool for relaxing, and basic French breakfast is absolutely free! 48 rue Rodier, 75009. For more info, hostels.com/hostels/paris/woodstock-hostel

Remember that great song, "You'll Never Walk Alone" from "Carousel: When you walk through the storm, hold your head up high and don't be afraid of the dark..."

We disagree! Senior travelers should be afraid of the dark! And if you're planning to roam by yourself, the first rule is, for safety's sake, never walk alone, especially in the dark. This is absolutely essential if you’re very elderly and physically challenged.

The world today is a far darker place than it was decades ago during student days, when you could backpack alone just about anywhere in the world. Remember happily traipsing through the Paris Latin Quarter, the Alps, the Gobi Desert, Greenwich Village, the Bund in Shanghai, Golden Gate Park, Acapulco waterfront, the Casbah in Marrakesh?

Q: We’re soon having a big family reunion in Las Vegas, and we’ll be gathering nearly 40 members from all over the U.S. and Mexico. Problem is some visitors and events will be in different hotels on the Strip.

They’re just short distances away, but many of us are elderly and can’t easily do the long walking from hotel to hotel. We also need scooters to navigate the long walks inside the big resort hotels. Are there electric scooter services in Vegas, and what are the prices? EMM, Santa Fe NM
