My wife and I toured all of Slovenia in summer of 2011 and started our trip in Izola. We loved it very much. The Hotel Marina was perfect and the staff great. We enjoyed our side trip to Koper and our visit to Piran and Portoroz. Your site is very helpful in reminding me of the names of the sites we saw.
Unfortunately, some of the descriptions in English need heavy editing by a native speaker. If you would like some help I wouold be willing to.
