Camping at 36 weeks

My SO and I have a one night camping trip planned for next weekend when I'll be 36 weeks. We're going to lay out on a huge tube on the lake and have a bonfire. I made sure the campsite is right next to the bathroom, we have a pop up camper and the campground is roughly 30 min from the hospital. However This is my first pregnancy and everyone tells me that the first tends to go late (I know people who have had their first early) though I'm kinda iffy on camping so late in this heat and I'm worried since my SO is planning on drinking so I'm worried if something happens he won't be able to drive.... Am I worrying for nothing??
