Please pick one from the packages that are available. If none of the packages suit the period you need, you can either extend the rental period later or simply get a longer package and return it a little early.

For example, if you need to rent for 8 days, you can buy 7 days package now and extend 1 day later, or buy 10 days package.

Tips: Depending on the period you need, it could be cheaper to get a longer package. For example, if you need it for 9 days, it is cheaper to get the 10 days package rather than the 7 days and extend it for 2 days. Please compare the prices and pick the best option for you. Check the extension rate on the following page: Extend Rental Period
