Ladies help can you please read!

My son is in second grade and he is turning 8 next month. For his birthday he wants him and four of his classmates ( all boys of course) to go camping for a night. I looked into it and me and my husband would rent out a tiny cabin in va beach for the night ... it's only a few miles from our school.( which is only $70 a night. Which is so much cheaper then $400 for a party at the zoo or something like Dave and busters) where we all live. Would you feel comfortable letting your boy go to the camp out birthday? I know when most of us were kids we would have sleep overs and it wouldn't be weird, but unfortunately times have changed. Also, for the feelings the other classmates. I would not send an invite. I would personally invite my phone call. I'm pregnant and no damn way would I sleep in a tent lol
