Glastonbury organisers are asking those going to the festival this year to pack as light as they can.
They say for security reasons there'll be extra searches of ticket holders and their bags and vehicles.
They're estimating that getting into the site in Somerset will be slower than in previous years.
According to their website, organisers say:
"For security reasons, all ticket holders will be subject to extra searches of their vehicles, their bags and their person at this year’s Festival.
"This will make entrance slower than in previous years. Please be patient if there are queues, and please cooperate with any security requests and all searches.
"We do appreciate that you’re going to be staying on the farm for several days, but the less you bring, the quicker you’ll get through the gates. As a general rule, we would ask you to only bring as much as you can carry yourself. It really will make things quicker.
"There will be separate search lanes for those with large luggage and trolleys, and we anticipate that these lanes will be significantly slower. So, please think: do you really need that camping chair? Can you manage without that extra food and drink? Remember, you can buy pretty much anything you need here on site.
"We would also ask you to put luggage tags on all of your bags and belongings with your name and mobile number, so that we can identify them as yours."
