Viator’s vetting of tour companies is poor. In Ketchikan Alaska they do business with a very shady company called Seaside Tours. They claim to be located at 121 Front Street which is not a valid address nor are they located in the Visitors Center (131 Front Street) as advertised on web site. We were inside Visitors Center before our tour meet time and no one had heard of them or 121 Front St. Finally one person had heard of them and stated they receive many complaints as they randomly move around meet spots unlike ‘legitimate tours’. Stick with tours that have been checked out by your cruise line. We learned the hard way.
