I have to purchase several services that I will use on different dates, how can I do it?

Follow points 1 and 2 of the normal purchasing procedure described in detail on the How to buy page and after you have added to your cart all the services you intend to start using on the day you arrive in Venice (point 2), click on the “Change” link at the top beside the date you had previously indicated. The link will redirect you to the calendar, where you will be able to select the new date (returning to point 1 of the purchasing procedure) and add to your cart the services you intend to start using on that day (point 2). Repeat the procedure if you want to select a third date and so on. When you have added all the services you require, continue the purchasing procedure (point 3) to complete it.
