This is the first time since 2008 that Kefalonia has made it into the Top 20. So, we recommend snapping up this £429-per-person deal from Inspired Luxury Escapes as we're not sure when this Greek island will next feature.
Saving up to £270 on the regular price, this is a chance to discover the island where Louis de Bernières' novel, Captain Corelli's Mandolin, is set. Unlike neighbouring Corfu, Kefalonia "remained unspoiled and largely unvisited", says the Daily Mail, calling it "secretive and spectacularly beautiful".
The price is based on travel from London Gatwick, London Luton, London Stansted and Manchester on select dates from 2-18 May and 28 September-5 October. Travel from Birmingham and Bristol on 2 and 9 May for £60 more per person. Here's what you get:
Perched on a hillside overlooking the Ionian Sea, the Mareblue Apostolata Resort & Spa has a large outdoor pool, two tennis courts, a fitness centre and a spa. The hotel is within easy reach of some of the island's best beaches and picturesque villages. Plus, a free shuttle is available.
Travel on select dates in June, July and September is £150 more per person. Click here for a list of exact dates and departure airports.
Travelzoo tip: Late May is the nesting season for Kefalonia's loggerhead turtle, so if you travel over these dates, keep your eyes peeled for this protected species. The beaches surrounding the hotel are prime nesting grounds.
Checked bags are from £35 more per bag.
