If you're anything like us, you've dreamed of flying to an island paradise, where the sand is soft and the sea sparkling as far as the eye can see. However, these idyllic destinations can get very expensive, due to their remoteness and high-end resorts. Don't despair, because we've come up with alternatives that allow you to find exotic loneliness without the prices that drain your bank accounts. Below, we've listed five of the most expensive islands in the world and offered a cheaper (and maybe even cooler) option for each one.

1. Swap Laucala Island for Castaway Island in Fiji

With its rugged jungle landscapes, turquoise waters and white sandy beaches, Fijiseem like the perfect place to relax. However, most people don't realize that this tropical paradise is made up of over 300 islands. If your vacation budget is unimaginable, then the very luxurious and private island of Laucala is a dream come true. An hour's flight from Fiji International Airport (with landing fees of around USD 10,000 if arriving by private jet), island accommodation consists of a series of luxury villas with swimming pools infinity edge and private beaches. The high prices also provide complete privacy and a setting that includes crystal-clear water and a beautiful coral reef. But with the cheapest room averaging nearly $ 5,000 a night (not to mention a three-night minimum stay requirement).

2. Hotel Arenella, Isola del Giglio

Located in Italy's Bay of Naples, Capri is a stunning island with jagged cliffs, a cave-lined coastline, plenty of designer boutiques, upscale hotels, and Michelin-starred restaurants. As well as being beautiful, the island can also be called expensive - a lot of boutique hotels here cost over $ 500 per night in high season.

Head further up the Italian coast to Isola del Giglio, where you can escape the crowds of tourists and the high prices. Ferries from the mainland take around an hour and cost around $ 80 each way, if you are traveling by car with two passengers. Popular with Italians, the Giglio is relatively unknown to tourists outside of Italy, but it made international news in 2015 when the Costa Concordia cruise ship ran aground just off the island. Expect to arrive by ferry in the quaint town of Giglio Porto, home to colorful houses and boats floating in the harbor. Much less chi-chi than Capri, Giglio still has a lot to offer, with its magnificent coastline, crystal-clear seas, its medieval hilltop town and a few mid-range hotels (100 to 200 USD per night) as well as a few high-end choices that cost nearly $ 300 per night. Giglio Porto is a lovely place to stroll and sample fantastic food, just like the hilltop town of Castello. The pretty little seaside resort of Giglio Campese has a superb beach and a number of reasonably priced restaurants. Overall a vacation on this island will make you feel like a local rather than being part of the tourist crowds elsewhere.

3. Beach at the Laluna hotel, Granada.

Necker Island, privately owned by British billionaire Sir Richard Branson, has become one of the world's greatest island getaways - and it obviously comes at a price. Branson bought the second-most northerly British Virgin Islands in 1978 for $ 180,000, but has since spent more than $ 10 million to make it an exclusive retreat. It now attracts all kinds of celebrities and entrepreneurs who are willing to shell out $ 42,000 per night (island-wide), or a more modest $ 27,000 per week if they book a villa. Previous guests include former US President Barack Obama. If it's still a bit below your price range, but you still want a Caribbean hideaway, Grenadais a more user-friendly option for wallets. Known as the Spice Island, Grenada is also one of the Caribbean's best kept secrets. It remains wonderfully unspoiled, with beautiful tropical forests, mountains and white sand beaches. And while you can spend your money here, it's not hard to find decent accommodation for less than $ 100 per night. For $ 20 you can enjoy a good meal at a tourist restaurant, and traditional weekend barbecues allow you to enjoy delicious food grilled on the street for just a few dollars a night. All in all, while you don't have the island to yourself, there are plenty of unspoiled places to explore.
