Hi Nicci,
I'm sure you'll like Greece and Halkidiki in particular. I've visited numerous resorts both on the mainland and on various Greek islands and never had a bad time. I've always found the people to be friendly, the scenery beatiful, the beaches clean and the local beer, especially the Mythos, gorgeous.
Me and my girlfriend have just returned from Halkidiki and really enjoyed it. We stayed 5 kms away from your resort in Hanioti. We spent a couple of days and nights in Pefkohori and really liked the relaxed atmosphere. There are a number of restaurants, bars and shops lining the 'front' opposite the beach so you'll be spoilt for choice. We had two very good meals but I can't remember the names of the places we ate at - not much help I know! There are also a number of restaurants and bars lining the main road through the town.
There was a funfair open in Pefkohori when we visited although I don't know if this is there permanently or not.
If you fancy visiting another resort Hanioti is only 5 euros in a taxi. We used to walk one way and get a taxi back the other. Polichrono is approx 10 kms away and this is another nice resort well worth visiting. Buses run all along the coast but we found these to be unreliable.
Hope this has been of some help.
Steve
