Up until now, Greek Island wedding packages have been the preserve of businesses at the luxury travel end of the market.
Many are based on the islands themselves and offer complete wedding packages with all the trimmings. Others spread the net wider and offer weddings in exotic locations all over the world.
Tripadvisor recently published its top ten wedding resorts in Greece, based on reviews by website visitors.

Getting married in Greece is not always a straightforward affair. Couples can face difficulties with the stringent requirements for personal documents.
If you do fancy a Greek island wedding you will need a full birth certificate and in relevant cases adoption certificates, divorce certificate and even death certificates if a previous spouse has died.
Document need to be legalised for use abroad through the Foreign & Commonwealth Office and translated into Greek by a recognised translator authorised and certified by the Greek Embassy in London.
Many couples like the idea of getting married in a Greek Orthodox Church or chapel, but this may require even more paperwork.
