Be it May/October, June/September or July the accommodation owners all over Arillas will welcome you like friends. The more often you visit the village the more you will make serious friendships like we have. Larger accommodation is available (eg Anna Studios have larger apartments, as do others.) Just email the owners and ask.
Sorry - the only month we have never been able to stay is May, but trust the reports of the many who have - they know the score. But I have it on good authority that the sea can be a lot cooler then, but still attractive to many. It warms up as the summer wears on and in October it can be lovely. I know that bit - I've done it. Depends what you want out of your time there.
Mirage is only one of seafront accommodation. The Horizon, Marina, Portofino, Marinaki and Kaloudis are all there too. And just a short walk further out there are many more. All appear on the interactive map so you can find out where you will be, whatever you book. Just go to maps in the website's menu to find it.
Like you we are still stuck with school term times, and pay a lot more. Newquay? Easy Jet out of Baltonsborough would suit us just great...
