If you’re using a laptop or iPad, make sure it’s on charge. Ensure you have the exact card and address details to hand.
Tickets are not reserved until you enter your details so you’ll want to nominate someone who’s quick at typing.
Don’t make the fatal mistake of trying to book using multiple browser tabs as this can upset the system. This is because most web browsers do not create a separate user session per tab – information is shared between all tabs for any given website. Open one tab, and persevere.
While it may be advised not to use more than one tab in a single browser, apparently using multiple browsers could be a wiser course of action. Think Chrome, Mozilla and Internet Explorer all open on one window (and one tab only).
If you’re able to join the virtual queue using multiple devices (think your phone, computer and tablet), then by all means give it a go to boost your chances of obtaining tickets.
Check how many tickets you are allowed to buy in one purchase. If you try to buy more than the limited number, your booking may be cancelled without notice, meaning nobody gets to go.
