Creative ways to hide alcohol in luggages (camping)

Hey guys, in a few weeks me and a few friends are going to a music festival and we need some creative ways to hide alcohol in our luggage bags when entering the camping grounds. Bottles ranging from wine bottles, beer bottles and spirit bottles. From what I've heard security is some what lenient.
Preferably without using money to buy fancy disguises and gimmicks, what are some ways to hide things in your luggage bags?

Put it near the bottom. Park rangers catch drunks based on them being loud idiots and everyone else complaining. You have nothing to worry about if you're either reasonably behaved or far enough away from other people that you won't bother them.

Yeah, just don't be a loud asshole and you won't get caught. It's not like airport security when entering a camping ground, they just wave you in.

Just don't be an asshole like other said and if just a bottle just wrap it in some clothes. Let alone they really check your stuff when you go camping?

I'm actually feeling somewhat confident in saying that they can't check your stuff when camping. At least in Canada park rangers do have police powers (ie, they can search your vehicle and camp site if they want to) but they also have better things to do than frisk teens/twenty-somethings coming into the park all day. I really don't think anyone other than a park ranger would ask to go through your stuff anyway.

There's always the classic method of switching labels or just putting alcohol in different bottles (such as Vodka in a water bottle, for instance). Obviously you should care to know what liquid is which before drinking it.

Generally though as others have said if you aren't rowdy and cause trouble you should be fine. Park rangers have no reason to mess with you unless they have a good reason to.
