Hello again.
I had a wee look into the cornucopia club, and the fact that they are employing your daughter, they should be responsible for her well being.
Like being an overseas rep they will have a doctor specifically for their employees and will supply her with a card or they will ask her to apply for a european health card it used to be an(e111) I think that has changed, but if you ask at the post office they will give you a form(free).
Normally companies who employ seasonal workers from the Uk won't let you go without one ! I am assuming she will be going out the middle of April, so you may be cutting it a wee bit fine doing it yourself, I think mine took about 6weeks.
Hope that is some help to you.
