If you want to go the best clubs, have a couple of drinks, eat in a top restaurants, live in a nice hotel in a good location, then Ibiza is an expensive holiday destination.
But there are some workarounds how to make your Ibiza holiday cheaper.Hotels:
Book and pay for accommodation in advance to get better price. Try to book your hotel in March or earlier. Don't choose the best location. There are many good and relatively cheap hotels within Ibiza Town.
Clubs:
Some clubs, including top clubs, offer cheaper tickets when you come there earlier. For example, ticket with entry before 1 AM is cheaper than regular ticket. Alternatively, you can go to mid-range clubs, that are also good.
Drinks:
In Ibiza, drinks are generally expensive. In clubs, the prices for drinks are very high. You can pay around 30 Eur per cocktail in top clubs. To save money, you can buy a drink package in some clubs. Common drink package is 5 drinks for 100 Eur. Drinks are more expensive in bars located close to the main strips or near the beach.
Restaurants:
Many restaurants are not too expensive. But it is recommended to have a breakfast in your hotel, because breakfast in cafés can easily cost you around 15 Eur. To save money, you can consider to pay for half-board or full-board at your hotel. Having a dinner at hotel is cheaper than going to restaurant. Restaurants located close to the main strips, near to the beach or tourist-frequent places are often more expensive.
Travelling:
Take bus instead of taxi. The are many bus routes. Not all the top clubs are situated in Ibiza Town, but there is an option to travel there by a public transport. The single bus journey costs around 3 Eur to 5 Eur. Check
