Cheltenham was just your average, sleepy town until the discovery of a spring in 1716, after which it became Britain's most popular spa town. (Like Palm Springs without the casinos.) Local Cheltonians have a reputation for being wealthy and respectable, and a walk along the Promenade will give you a first-class view of their wonderful houses, shops and gardens. After taking in the waters at the Pittville Pump Room (great name for a spa), check out the Art Gallery and Museum to learn about the social history of Cheltenham.

Lefkada's name means "white," from the famous white cliffs of Cape Lefkata, site of an ancient temple of Apollo, where rumor has it that the celebrated Lesbian poet Sappho flung herself from the rocks. To stay with the mythology theme, don’t miss a boat tour on the mighty Odysseia, a colorful replica of a Greek war ship. You can also explore deserted monasteries in the mountains, splash around under the Nidri waterfalls and swim at some of Greece's most famous and beautiful beaches.

The “Red City” of Marrakesh is a magical place, brimming with markets, gardens, palaces, and mosques. Exploring the intimate courtyards and snaking alleyways of the historic Medina can easily eat up a day. Find inner peace at the serene Jardin Majorelle or take in the beauty of one of the city’s historic mosques (taking note that, unless you are Muslim, you are not allowed to enter).

The Pearl of the Mediterranean has an ambiance more in keeping with its neighbours to the north than with those in the Middle East. Site of Pharos lighthouse, one of the Wonders of the World, and of Anthony and Cleopatra’s tempestuous romance, the city was founded by Alexander the Great in 331 BCE. Today, Alexandria offers fascinating insights into its proud Greek past, as well as interesting mosques, the casino strip of the Corniche, some lovely gardens and both modern and traditional hotels.

If you're currently planning a trip to Egypt, please consider the risks and monitor your government's travel alerts.)
