After celebrating their wedding wows, most couples will jet out of town and enjoy their first trip as a married couple.
Known as the honeymoon, newly-weds can splurge a whopping three times more on average than other travelling couples, according to About.com, and the trip can make up about 14 per cent of the wedding budget.
Just how can a honeymoon holiday turn out so expensive? Well, the recently-married duo might have selected one of these seven most expensive honeymoon destinations in the world, compiled by Oyster.com.
If you were thinking these places include London, New York or Paris - you'll be surprised that none of these pricey holiday spots made the list.
If privacy is the couple's top priority, then Kauai - Hawaii's smallest and least developed island, is the best choice, Oyster.com recommends.
With a lush and mountainous terrain setting, Kauai lets newly-weds enjoy an unadulterated nature paradise to unwind from their wedding festivities.
Bask under the sun or indulge in the many sea sports available; the islands has tons of activities to fill the days.
Another island paradise worth mentioning which is also on this luxury list is Fiji. If you enjoyed the bottled Fuji water, wait till you and your spouse head over there to enjoy the abundant offerings of freshly-caught seafood and tropical fruits.
A popular holiday spot for Australians, the airfare alone will put a dent in your bank account if you are flying in from elsewhere in the world, according to Oyster.com.
Like Kauai, honeymooners can enjoy many island activities from helicopter tours to skydiving, as well as decadent spa and relaxation offerings.
Not all expensive spots are tucked away in seclusion. Tuscany - touted as one of the world's most stunning wine regions - is another luxury honeymoon spot for those who want to splurge.
With rolling hills, historic estates and gastronomically fresh and delicious food, Tuscany is one of the best and most romantic places to celebrate a marriage union.
