Although 8 people can fit into an 8 person tent, you’ll likely want to opt for a larger tent for more space and comfort. A 12 person tent would likely be a better option. Alternatively, you might want to split the group across two 6 person tents. Keep in mind that, the longer you’re camping for, the more important it’s going to be to have plenty of space – for all your gear and also for rainy or cold days when you want to hang out in the tent.
