hi,
Sorry it has taken so long to reply to your post. We wen to the Galini in August of this year and it never appeared in the Olympic brochure. I've noticed this before, in other resorts, they can only advertise so many places in their brochures so they tend to advertise the others on the website only.
To further complicate things, I also think that they wait until their preferred accommodation is booked up before they start to advertise the cheaper places. I can only suggest that you keep looking at the website.
