need to fallow several paths. First of all, choose proper term for your cheap flights Italy is really hot land, so you do not need to visit it during hot season (in a recent article). Go there in June an September and you get a lot better deal not just on flights but also on accommodation. Also, there will be less tourists on the streets, so you will have a chance to relax more. The most famous destination is Rome, but you can also travel to Milan or Florence.
Another good alternative is to reserve flights to Slovenia. That is maybe not really popular destination from Poland, but it is really worth to be checked. This country got a great wildlife, nice towns with amazing attractions, tasty cuisine and friendly citizens. Even if this land is so tiny, it has all types of attractions. If you want to lay on a sand all day, you will find there nice
resorts by a seaside (keep your finger on the pulse). If you prefer to climb on a hills, you can use some of traveler’s tracks within the Alps.
