Olympic Holidays has added Madeira, La Palma and Cape Verde to its newly launched summer 2018 programme.
Bookings are now being taken for the programme, which runs from May-October 2018.
Family options have also been extended, to include deals for families of all sizes and situations and there are advance offers of two weeks for the price of one.
Also in the programme is the three-star-plus Horizon Beach Hotel, Crete, which is exclusive to Olympic.
Chief commercial officer Clare Tobin said: "Olympic Holidays continues expand the variety of islands we offer, drawing on our 50 years of expertise in the Med and beyond.
"Our family options not only cover all budget levels but ensure that all modern family variations can find a deal.
"Our island hopper packages offer two or even three holidays in one, with contrasting experiences available in one and two week deals."
