A number of coastal resorts in Bulgaria will start functioning only in mid-June, Sega daily reported. The financial crisis and the lack of sufficient number of tourists is leading to this delay in the start of the summer season, head of the Sunny Beach union of owners Elena Ivanova said. Bookings in northern Black Sea resorts register 15 to 20 percent lower levels than the bookings for the same period of 2008. The decrease could be overcome through the bookings of Romanian tourists.
