Do plan time before or after your cruise to explore San Diego. The B Street Terminal Cruise Port enjoys a prime downtown San Diego location, a short distance away from Little Italy, the Gaslamp Quarter and even the Point Loma neighborhood. Translation: Take advantage of the fact you'll already be in the thick of things.
Attractions on this list include a few tours that can give cruisers without the luxury of several days in San Diego a quick overview of the city. While Another Side of San Diego can arrange basically anything you'd like from Segways to helicopter tours, hopping on and off the signature orange Old Town Trolley is easy, because it stops in front of the Maritime Museum, also a must-see. The trolley tours are a hop on and hop off situation, taking guests to Old Town or even as far north as scenic La Jolla.
Or, hop on a SEAL Tour. The funky, amphibious bus-boats start on land, touring a number of San Diego's photo-worthy sights and end up in the San Diego Bay where guests enjoy almost eye-level photos with wildlife, including seals and sea lions.
Whether your stay in San Diego is long or just a few hours, an attraction or two on this list will keep you happily occupied.
