Through your personal Eventbrite account, it is possible to upgrade your tickets for a small fee, this is called a “transfer”. You can upgrade a ticket for a single day to a Weekend ticket or upgrade your Sunday ticket to a Saturday ticket. You can change a parking ticket without the need to pay a fee.
Please note that for each ticket there are two price tiers, with and without a discount for kids. Unfortunately Eventbrite doesn’t make this clear in the transfer proces, be aware to select the highest price variety if your upgrading a ticket for adults.
NB: Two separate day tickets for Saturday and Sunday are not equal to a Weekend ticket and will not grant you a wristband and passport.
