Just got back home after 10 days in Arillas, got to agree with Eggy on this subject, the girls who run the sunbeds ( Angella and Rula ) have been doing a fantastic job for years and the fee they have to pay to the powers that be for the rental of the beach is huge, they did tell me but I won't repeat it here.
7.50 euros for 2 beds and 2 brollies and a table, ashtray too if needed is great value in my book for as well as a bit of comfort and shade you are supporting local people by putting a bit of cash in the pot as some other nationalitys have a culture of throwing a rolled up mat on the beach , which is there choice by the way.
Come on , The good people of Arillas need us ...Get Off me soap box now, great holiday too, hope to go back end of August.
Cheers Chris.
