Alex's knowledge and skill set was perfect in helping to arrange our trip with Viking River Cruise. Her knowledge of all the things that made life easier when travelling with my mom who uses a walker. Alex was able to help my mom cross an item off her bucket list, given that my mom has cancer that is a huge accomplishment. Hats off to Viking River Cruise as well for offering full refund on the trip if necessary as that was also a consideration when we were booking. All in all a trip of life time and I would do it again.
