Last year, I visited in Paris, Rome, Switzerland and Zurich. I was 13 days in these countries and my full trip organised by Fly Time Tours and Travel Inc.
Well, i was going to say forget Ibiza, as the other cities have so much more to offer. However, since your interests include beaches and nightlife, well, then I'd say forget Rome.
This information is really good for traveller to knowing. It is true that Europe is the world's famous holiday destination where so many of tourist attraction points. Paris, London, Venice, Madrid, Frankfurt and Rome are my favourite holiday destination in Europe.
Barcelona Spain, London England, Amsterdam Netherlands, Dublin Ireland, Bergen Norway, Seville Spain, Cinque Terre Italy all these are the places to must visit.
