Decorating Your Camp Site

So last year myself and a couple of my boys went sort of in the most rushed and last minute way. It was also the first festival for two of us. Since I have more time to plan this year and will have a much larger group, I was curious what way you guys dress up your camp. I really want to get some tapestries and lighting and was wondering if anyone had any suggestions on the best place to go for those sort of things. I was looking at some rope lighting as I would like to have our place illuminated for when I get back and late night events. Do the battery powered ones burn out the batteries fast, will they make it from when I turn them on leaving camp to when I get back at say 4 am? In addition what other crazy fun things are a must to have at the camp site? I want it to be inviting for others to be able to stroll through and join if they feel inclined. Any suggestions would be helpful.
