Mr. Wonderful and I are considering a cruise to Alaska next year. We have primarily been independent travelers but loved our one and only ocean cruise on Viking. We are considering Viking to Alaska but they have only one itinerary. Are there other cruise lines to Alaska comparable to Viking that we should consider? We liked Viking's cabin comfort, excursion options, spa, opportunity to dine outside on deck and included specialty restaurants. We are not interested in a casino or a huge ship. Thanks in advance for your advice.
