So many tips here that I live by. After 5 years on the road I came to #4 (kids). Recently had a month in USA and happily did #12 (blow budget) but we have come back and said to ourselves that it’s not really worth those massive big budget blowing trips with our little one only being 2 yo (almost 3) as she can get great fun out of almost anything. We took her to Disneyland and her best time was a bench seat that had old tractor seats on it!
Sharing Space: It may be awkward to share quarters with your colleague, but take it in stride and make the best of it. Be polite and give them privacy when they ask. Avoid using shared spaces such as the bathroom for extended periods. Get dressed and undressed in a private space to avoid awkward encounters. Offer to leave the room for a half-hour or so while they get ready. Hopefully they’ll get the hint and return the favor.
Be a regular, not just another, guest. Too often, business travelers play the "points" game to get the perks at all properties or the points for family vacations. I've changed that approach and become "property" loyal as a regular. What do I get out of that? I get the best in house upgrade all the time, at the same rate of a regular room, VIP Lounge access, and free Internet all the time. I even get rooms when the hotel is sold out, at my regular rate. At other properties, the hotel GM has me treated like a VIP.
Though Amtrak is the largest train service in the state, it’s not the only way to roll. In Northern California, Caltrain has regular service between San Francisco and San Jose. In Southern California, Metrolink offers service on seven regional lines that connect L.A., Ventura County, Antelope Valley, San Bernardino, Riverside, Orange County, and the Inland Empire. Trains dedicated to certain themes and in specific locales, such as the Napa Valley Wine Train, also provide a unique way to see some of California’s premier destinations.
