Kings, queens and statesmen were guests aboard in the 1930s. GIs on the way to war and home again in the 1940s sailed on the mighty ship. Although she’s now permanently moored in the harbor, you can get the feel of cruising the ocean waves by enlisting to be aboard for a night or more.

Today the Queen Mary is an Art Deco Hotel on the waterfront, with more than 300 cabins and suites. She offers on-board programs, special events, educational tours, colorful shops, upscale restaurants and banquet facilities. Overnight room rates start at $100.

It’s not too creepy if you’re nostalgically interested in entertainment history. On your next visit to the Los Angeles area, spend an hour or two visiting the last resting places of some of the famed people from your earlier years. Among several celebrity cemeteries in the Los Angeles area is the branch of Forest Lawn in the Hollywood Hills above the city.

It’s near Disney, Universal and Warner Brothers Studios. Among graves in the Memorial Park, seek out those where you can pause and remember. They include Debbie Reynolds, Carrie Fisher, Bette Davis, Lucille Ball, Telly Savalas, Buster Keaton, Dorothy Lamour, Liberace, Freddie Prinze, Jack Webb, Stan Laurel, Ricky Nelson, Gene Autry and Sandra Dee. One of several tour companies that offer daily visits to the cemetery is hollywoodcitytours.com.

There are overwhelming numbers of thoughtless tourists with smartphones these days. The selfie has become an annoying reality in the world of travel. No monument or statue is safe from thoughtless point-and-shooters crawling all over them and posing.

Other world-respected statues have suffered the same disgraceful behavior. Think of David in Florence, Admiral Nelson in London, the Little Mermaid in Copenhagen, the peeing boy in Brussels and many others. Before you attempt some offensive climbing and posing, know the local rules. If you do it on Easter Island, it could cost you $500 and/or some time in the local hoosegow.

Even though you were quoted a price that included a senior discount when originally booking with a travel agent or online, speak up. When actually eye-to-eye checking in at the hotel front desk, ask if there’s an additional senior discount in effect.

Additionally, when your room is being assigned, further ask if you’re eligible for a free upgrade to a larger room or suite. It can be more effective if you declare you’re celebrating an important event, such as birthday, anniversary or are newly retired.

Some hotel chains regularly offer senior discounts, including Best Western, Choice Hotels, Comfort Inn, Crowne Plaza, Hyatt, La Quinta, Marriott, Omni Hotels and Resorts, Red Roof Inns and Wyndham Hotel Group.
