i'm looking at going on a contiki tour to europe in august and there's a choice of concept tour (share with 3 other girls, hostels/cabin, bit cheaper) or time out tour (share with 1 other girl or single room, hotels, dearer). i am an australian girl going on my own, which tour should i take? i don't mind spening a bit extra. does anyone know which tours have more single people / solo travellers/ australians ? any experiences to share?
