This is the email address we used to advise security.
'condado.seguridad@securitas.es'
I suggest they take a copy of this with them to show security when they arrive. They will also have to show their passports etc. However, if you have one of the cards given to you by Mileniun, then they can just swipe this against the machine, if it's working of course!
Please bear in mind, if they haven't got one of these, then they will have to show their passports each time they want to get into the resort.
