Hello Claire,
You are not being a pain at all, we are all here to help each other make the most of their holiday in Arillas.
I'm sure that one of the Marina regulars will be able to confirm this, but I had heard that they are now contracted to a European tour operator.
The Marina owners also have superb apartments at the far end of the seafront (the nudie end). My sister and brother-in-law stayed in them soon after they opened in 2004 and I can vouch for their fab location and facilities. Bear in mind this does mean doing flight only. If considering flight only there are other apartments on the seafront, for example the Portofino or Alex's (above/behind minimarket).
To book the Marina apartments (called Marinaki) direct, or to enquire who to book the hotel through you can email them here: arillashotelmarina@yahoo.gr or you can ring them on 0030 26630 51100, 51102, 51103 or 0030 26610 91786
There are new apartments opening this year next to the Mirage, called incidently...The Mirage apts! They are bookable through Thomas Cook.
Then there is the Horizon hotel on the seafront, bookable through Libra.
Good luck,
Eileenx
