With its scenic coastline extending around the Baja Peninsula, western Mexico consists of three states and a petite grouping of islands. An experience on Mexico's Gold Coast may include lounging on the beach, kayaking a sandbar, exploring Mayan ruins or dancing in trendy nightclubs. Mazatlan offers a more traditional cultural experience, while Puerto Vallarta and Cabo San Lucas are especially accommodating to cruisers looking to shop or head to local restaurant and bars.
You've decided you want a vacation, but there's a problem -- you don't have a passport. Maybe you've never had the time, money or desire to travel abroad previously, or perhaps your old passport has expired. Whatever the reason, you still have choices. One option is to take a closed-loop cruise -- a round-trip sailing that leaves from and returns to the same U.S. port. For that, you need only a birth certificate and a driver's license (or other acceptable, government-issued photo ID). You can't cruise just anywhere on a closed-loop sailing, but the choices are more interesting than you might expect. Below, we've compiled a list of seven places to visit without a passport, from scenic Alaska to the beachy Caribbean.
