Because of the attacks, restrictions and general nervousness across Europe?
We had several hundred people at an event in Madrid when they were attacked and although no-one from our company was hurt or even involved, we lost contact with them for a while and logistically it was a bit of a nightmare/not particularly well handled. Families contacting us because they couldn't contact loved ones either and we had nothing to tell them.
I don't know if we're particularly nervous because of that experience, or whether it would be right and proper to put some travel restrictions in place now. What are other companies doing?
Ultimately, it won't be my decision but I've been asked to contribute.
