PENNINGTON, N.J., Sept. 13, 2012 /PRNewswire/ -- As the expansion of river cruise fleets continues, Cruise Critic® ( http://www.cruisecritic.com), has launched a new river cruise resource ( http://www.cruisecritic.com/river) to help travelers compare ships and cruise lines. Carolyn Spencer Brown, Cruise Critic editor-in-chief explains, "River cruise lines have made huge strides in improving their offerings across the board -- from new ships and major refurbishments to improved service and a greater variety of tour options. Because of this, we're seeing more distinction between the individual lines, and each is suited to a slightly different traveler. So, we're providing information on Cruise Critic that will help people choose the right ship and itinerary, to suit their preferences." Cruise Critic, which offers information, reviews and ratings for more than 380 cruise ships, has recently added new information about popular river cruise regions, cruise lines and ships, as well as river cruise deals. "We're seeing an upswing in interest in this sector, especially from experienced ocean cruisers looking for a way to visit new regions and bucket list destinations," Spencer Brown adds. "European rivers are incredibly popular, and there's growing interest in exotic cruises along the Mekong and Yangtze rivers, Amazon cruises and Nile trips. The revival of Mississippi river cruises has also renewed interest in exploring regions closer to home." Based on commonly asked questions about river cruising, Cruise Critic shares these five things to know about river cruising: Is One River Ship Much the Same as Another? No. Most river cruise ships look similar in terms of size because the length, breadth and even the height of the ship is limited by the rivers they sail -- and bridges and locks they must navigate. However, the external similarities hide the significant differences that one experiences onboard. Atmosphere and service vary greatly, as does design and decor. Some cruise lines opt for a sleek, minimalist style to create more space in cabins and public areas of the ship, whereas others fill every inch with sumptuous furnishings and decor.
