OK, it's a first world problem, but can anyone recommend ear plugs which will block loud snoring? I'm sharing space with my cousin who snores like a tractor and what little sleep I get over the festival is reduced further. I've read reviews of those that reduce noise to allow you to hear music, but I'm after some that block more /all noise and the type you get at the festival, or the gel type don't work like that. Thanks for any reviews and recommendations.
