I spent Friday night and Saturday morning queueing at Wimbledon! It would’ve been ten times better had it not rained near-continuously on the Saturday, but it was still marvellous fun nonetheless.

This site about queueing was helpful. I have a couple of additions based on our experience.

1. For the love of God, bring a tent. The party of 5 next to us in the queue didn’t, and they spent all night in the cold, in the rain, in the open, being laughed at by us. They banged on our tent door, begging for our mercy, pleading with us just to let one of their party in before the frostbite, wombles and chavs ate them alive, but we held fast, knowing that every one of them that perished shifted us one step closer to Centre Court tickets.
2. Bring a pop-up tent. They’re more expensive than the poles-and-pegs variety, and it’s worth every penny to have your tent up and running in 4 seconds. It would’ve taken 2 seconds but we hadn’t read the instructions beforehand. While our laughter at the poor souls upqueue from us was part of our plan to improve our ticket-getting odds, our laughter at the poor souls downqueue was because it took them an hour and a half to put up their tent. They were fortunate that it didn’t start raining until later. Furthermore, you are woken up by the stewards early enough as it is. You don’t want to spend your valuable waking up time struggling to put a recalcitrant tent away.
3. At the very least, bring a tent that stays upright on its own. You can’t guarantee queueing in the park, so you might have to pitch on the pavement, which is not going to work if your tent relies on ropes and pegs being hammered into the ground. Some say you can tie your tent to the fence, but you’re not guaranteed to be near a fence, and that only works on one side.
4. Bring earplugs if you like it to be quiet when you sleep.
5. You don’t need anything in the grounds. Food, water, waterproof coats, cushions, umbrellas, towels, and more, are all on sale at the shops within. The catch is that it’s all rather expensive, and the anti-catch is that anything you bring in yourself will be extra bulk and hassle to carry around. So make the trade-off according to your budget, and how many arms you have.
