We're looking at the resort in Lemnos. We're not sailors although will probably have a go at kayaking but the rest of it - accom, facilities, the local town - all looks nice. We did Mark Warner in Sardinia last year which was lovely but isolated - there was no town anywhere near and nowhere to visit, and the accommodation was fine but your outside terrace was gloomy. It's be great to hear from anyone who has done an alternative that they would recommend; we're looking for enough activity to keep two energetic young boys happy, with nice personal space and facilities and near enough to something else to escape for a day if we start to feel cabin fever!
