If you are going out with a group of friends or playing escort for the company, then a minibus rental is your best option. It is only logical to hire a minibus when more than four people are going anywhere together. It only requires one driver and it means no one is left out or behind. Not to mention it is cheaper than hiring multiple taxis.
An important benefit of a minibus is that it only needs one driver. There is no need to hail multiple taxis or follow each other. This means only one person needs to know where they are going. For parties, one driver means more time having fun and less time locating a ride home. Plus, everybody gets in the same car allowing the fun to continue with no one being left out or behind.
Most rental car agencies have some sort of minibus available to rent. For the best deals, you need to do a little research as prices vary by company and by date. Like anything else, making a reservation in advance can save you both time and money. Waiting to the last minute or worse waiting till you are at the rental agency, will cost you more in the long run. It is always best to reserve the minibus at least a week in advance but the more notice you have the better deal you will find.
The requirements to hire a minibus are similar to renting a car. You will need a valid driver's license and a credit card. The majority of rental car agencies will charge more if the driver is under 25 because they pose a higher risk. However, some rental car agency will rent a minibus to those as young as 21, just expect to pay more.
