I do not think they will change their minds. You might get some sort of special offers mid Season onwards after they evaluate attendances. Their mind is made up on the 14 day pass.... it was abused by many and they tried to make it foolproof which proved unsuccesful.
If I see or hear of anything I will repost

Thats a real shame I dont know why they cant just take a photo on your first visit then the tickets would need to be used by the ticket holder.

I have boughht the 14 day pass on my previous 3 visits to Salou and had intended to this year but there is no way I can afford to at the price its at now.
