At start, the most important is date. If you want to travel for a song, try to avoid hot season, such as summertime for example Cause during this period of year, the weather is the best, therefore most of travelers better like to go to Japan then. If you just want to take a trip, see a lot of local monuments, you should enjoy spring or autumn. Just avoid winter, because Japan is an Island, so it will be raining all day long.
More local, but either interesting is Croatia. When you wish to go there for a holidays in the time of the best temperature, greatest is to book cheap flights to Zagreb. This place is not situated close to the sea, so this connection is far less popular then to
Split and Dubrovnik (by far the more you can read at this address). Thanks to that, you have a chance to get the finest deal, even during famous season. And it isn’t hard to travel from Zagreb to seaside, you just have to rent a car or use a train. It’s going strictly from the airfield to the main resorts.
