Mark Twain. Two of the sweetest words a riverman can hear. We would submit that that’s not only because of the water’s depth either. Boarding the Mark Twain for an excursion around the Rivers of America is one of the sweetest, most relaxing rides at Disneyland. The whistle and the steady puff of steam are the serene soundtrack for your voyage, unlike that pesky Sailing Ship Columbia and the canon they fire in hopes of making you jump in front of your friends or spill the last bites of your sandwich into the river for the ducks. So if it’s a placid and pleasant journey through the frontier you’re after, “Mark Twain” are the sweetest words you’ll hear… not Columbia.
