I e-mailed Eyal in Israel and immediately he replied:
Thank you for your email. I assure you your email is totally natural.
I'll speak tomorrow with the madrichim and ask them about this issue. They are well trained to deal with issues like this, and did it more then once in the past. Joelle will probably call you tomorrow or in Friday. She was not able to call you in the last days due to the fact that they have been in places without phones (survival in the dessert and Masada the day before). Now, when the arrive to Eilat she will have a lot of opportunities to call you.
Please, don't hesitate to contact me by phone or by email with any question or worry.
Have a nice evening,
