Hi there. I had my first Just You holiday to the Cilento Coast in Italy in May. I hadn't had a package holiday in years, as normally I travel to meet friends, and this part of Italy was unknown to me, although I have been to the Neapolitan Riviera many times, and also to Rome, Sicily, Milan, the Italian Riviera and Lake Como.
It's a beautiful place, the hotel was great with very few negative factors. People are generally friendly, and having been abroad on my own numerous times I enjoyed particulary having the company if I needed at night and at meal times.
Other parts of Europe? I haven't been to France, but Croatia is nice, Rabac the resort Just You use is lovely.
Hope that has helped a bit. Sorry I can't help more. I am always commited to Italy if I go on holiday in Europe.
