Prefer to do your traveling alone? So long as you avoid all-inclusive resorts and vacation packages (which base their prices on double occupancy), you likely won't face the dreaded "single supplement," a penalty added to the base price of a room or package. For more information, pick up Eleanor Berman's latest edition of Traveling Solo: Advice and Ideas for More Than 250 Great Vacations (Globe Pequot, 2008), a guide with advice on traveling alone, either solo or as part of a group tour.
If, like John Steinbeck, you want to take your dog (or cat, or whatever) with you for companionship on your travels, many hotels across the U.S. (for example, all Motel 6 properties) will be happy to roll out the welcome mat for your pet.
