Hi- Need a help. Am planning to do a 2 day bus tour between NYC and Niagara falls during Sep 2014. The price of Viator tour is 320 USD whereas that for 'Get Bus Tours' is 160 USD. The itinerary is almost same and the overnight hotel is also same; not sure whats the reason for the price difference . Can someone help me choose ? Viator is charging twice of other tour operators and am not sure why ? Would the bus quality be same ?
