Hi Karen Mouse (Lucky your name wasn't Minnie!!) LOL
Regarding the Athina Hotel; I have stayed there twice and my brother 3 times, over the years.
They do not usually offer the option of Lunch instead of Dinner,
they may do a pack lunch if you have booked an excursion, but this would have to be negotiated, and collected in the Morning.
They definately would not allow us to have lunch in the pool bar instead of dinner, when we stayed there.
My advice is to ask - you may get lucky if you ask nicely, find the owner/manager and ask him, directly.
He usually sits on a stool at the end of the Bar during Dinner, but don't get your hopes up too high!
Regarding the Nudie Beach,
as you walk through the Athina, past the pool and onto the Beach, the Nudie Beach is to the right,
and generally starts just before the visible end of the beach, where it's quite wide and they usually go towards the back of the beach.
If you were to walk there, the Naturists will be found in various spots along the next section of beach around the bend
and under the cliffs. They often have small sun-tents and never use the beach beds, so its past the last of the beach beds.
The rest of the beach is mixed costume and topless, the least amount of topless bathing is often to the left in front of the
Waves Restaurant - to Manthos Taverna section - but you may still find some topless there as well.
I hope this helps
I hope you have a great Holiday
When are you going?
We will be there in early Sept.
Best Regards and welcome to the Forum
