Along freeways with heavy traffic, carpool lanes (also called “diamond lanes” for the diamond-shape pattern painted on the lane’s surfaces) are identified by black-and-white signs that include details on times and days of enforcement (usually during peak rush hour periods on weekdays). To drive in most carpool lanes, you must at least two people (including the driver) in the car (some lanes in the San Francisco Bay Area have a three-person minimum. Tempted to use the lane when you don’t have the required number of riders? Don’t—fines are staggeringly high, close to $400 in some areas. In the Los Angeles area, carpool lanes may have specific entry and exit zones; adhere to them or you could get a hefty fine. 
As a productivity trainer, I travel quite frequently. Sometimes, there can be quite a bit of downtime. It could be long delays between flights or canceled flights requiring you to rebook on a later flight. This often causes travelers a great deal of stress. But, don’t fear downtime. If your flight gets delayed, you might default to checking your email or doing other work. However, it may be more productive to use this unexpected time to meditate or just let your mind wander. This kind of mental break boosts your productivity and creativity.

Your tips are great, and I definitely agree with #1. Like you, we started off traveling as a couple. In fact, we met when we were both backpacking through Southeast Asia, specifically Vietnam. Now that we have a toddler, we tend to pick family-friendly vacation destinations. This year, we traveled to Barbados for two weeks. The beaches are amazing, the food is awesome, and most importantly, the locals are very friendly.


I love getting to explore a new place during a layover, and will almost always extend my travel day so that I can spend three or four days in a new city. Some of my layover highlights from the past five years include 48 hours exploring the Golden Circle in Iceland, spending a few days getting lost in Muscat, and when I spent 24 hours in Abu Dhabi just so I could take photos of the Sheikh Zayed Mosque.
As I mention above, every minute you pass without a seat assignment is another minute that your aisle or window seat is given to someone else. Your best bet is to check in online, which can typically be done up to 24 hours before your flight. But note that not all flights, airlines or classes of travel permit advance check-in (or seating assignments).
Great list of tips! I do have to say that I have been very thankful in the past for a nearby McDonald’s. Years ago when I was not a very experienced traveler, I arrived on a train by myself in Munich. I don’t speak German beyond a very few basic phrases. The train station is large with numerous exit doors. I knew where I wanted to go but didn’t know which door to take that would put me in the right direction. After standing there indecisively for some time, I realized that I would simply have to select a door and go out. When I did exit, the sight of golden arches about 2-3 blocks away was most welcome. I knew that I could go there, order some coffee or perhaps something else breakfast-like and study my map to orient myself. It turned out that I had selected the best door to exit, but it was the ability to sit somewhere somewhat familiar that gave me the confidence to carry on with my travel plans. I agree with several other posters, too, that McDonald’s can be depended upon to have clean bathrooms, often the only ones available.

Whether it’s that steamy romance novel, thrilling sci-fi, or a dog-eared travel guide, download it before your trip.  Even if at home you’re a paper-til-I-die sort, save the space and weight for your holiday.  And don’t count on wi-fi to jump back into the story from your perfectly positioned beach chair.  Make sure it’s on a water-resistent covered device (check out Otterbox for some serious protection for your cherished e-reader, phone or tablet).
