No, it does not. Whilst you add shows to your planner, there is no timer or time limit because you have not requested seats.At this point you cannot be guaranteed seats for the shows you choose.
Once you proceed to request tickets for the individual shows in your planner, the 15 minute window period for payment starts
Remember that every time a new item is added to your basket (not planner) or an existing item is changed in the basket, the timer resets to 15 minutes.

The festival planner is available under the category FESTIVALS on www.computicket.com. This is a calendar where you can list all the performances you plan to go and see during a festival. The planner / calendar will point out any double entries to ensure that you do not have a double booking on a specific day or at a specific time. Proceed to the individual event, request and process payment. You now have the assurance that the events you booked for will not clash with another event time and date.
