Wiethoofdsamifacelast year they were very chill about not checking bags people brought in. stop at a netto and grab some liqour and you're all set.Completely different venue and security this year most likely, so bringing in food/drinks is at your own risk (as it already was), but more common sense pricing for the food and drink stands and bar in the venue should also help.
iirc it was cpg security checking in/out but you're right, especially with more recent security concerns developing it's likely they aren't as free as they were last year. altogether though, if we're going to be there for 14 hours it is a huge plus to have affordable (not to mention edible) food on site, and it is a very welcome change.
edit: sorry just did the math on updated schedule
