Our train from Paris experienced technical difficulties and was removed from service – leaving us on an empty train platform with zero idea of when we’d eventually arrive in Barcelona. I messaged Viator and was connected to the Tour Operator who remained in contact with me as the saga unfolded. When we were finally on our way, I was advised that the driver had been provided our updated arrival information – and he met us as originally planned. I genuinely appreciated the Tour Operator’s responsiveness – it went a long way to turning around what had been a very stressful day.
