You are responsible for organising your own travel (including visas if necessary) to and from the start and end of the trip. You are also responsible for organising your own travel insurance (having travel insurance is a requirement of the trip). Apart from that, everything else is included. There are many different offers and packages available for Sicily - all with different combinations of half-board/full-board and what is and is not included. As a result, choosing a trip can be very confusing, and choosing a non-inclusive package can easily end up far more expensive than the inclusive option.
