Of course, the problem with having a magical tent was needing magic to pitch it. Yes, it was theoretically possible to put it up without magic, but she didn't seem to possess enough hands or the necessary wingspan to do it by herself. Malfoy found it amusing to learn she carried around a perfectly safe shelter with her everywhere she went. He'd had fond memories of sleeping in tents as a young child. Knowing he wouldn't have to bother with the ridiculous peacocks his father always insisted on bringing with them everywhere they went was a relief. He didn't waste any time setting it up in the middle of a forest Hermione was unfamiliar with and casting the necessary charms to keep them concealed.
