Hope you don't need help.
When the flight home was cancelled we received no support with re-booking flights and were left to sort it out on our own. A hotel was provided for the group but no follow up was made. In the 3 days we were sat waiting for the new flights home nobody from the company contacted the group to check in. And in fact we all received "welcome home" emails while our children were still stranded on their trip. When I send my child on a school tour I expect help when things go wrong not a good luck and a wave.
