Hi Cornerhouse
Are you in for a treat ? I spent three weeks in Arillas in August -as I have done every year for the past 12 years.
I don't know about Kaloudis Village and wi-fi but you can pick up Wi-fi at the Marina Hotel, the Horizon Hotel, Bardis Sun, Dimitri's and probably lots more places, mostly free if you buy a drink. There is also access at Mirage and the Coconut Bar on their pc's but you have to pay 2 euros for 16 minutes, I think.
Creature Comforts ? A jacket or cardigan for the evenings so late in the season, otherwise swimwear, shorts, T-shirts, flip-flops etc. Nowhere is very smart.
I don't know about the mossies in October but in August they were hardly to be seen. Just as well to have a plug-in in your room at night, however, and to 'deet' up before you go out at night. You can get all that stuff at either of the supermarkets. I always take my own coffee and breakfast cereal because the coffee is not to my taste, and the cereals are very expensive. I also don't like any of the Greek crackers (all a bit sweet) so I always take a packet of ryvita.
Otherwise ? Nothing I can think of. It is a very relaxed place, you'll meet lovely people - everyone has a permanent smile on their face - and eat scrumptious food from a big choice of tavernas. have a great time ! JC
