I reckon don't get too worried about whether or not you're taking too much.
If you have a trailer and the fg then you have more space than you need anyway so take whatever.
You will soon work out what you didn't really need, and what you should take next time.
First time out, especially with three women, better of to have too much stuff than not enough.

Oh, one thing to check when you book your site. Some don't allow to use local wood for fires, no sticks, fallen branches, 'accidentally' fallen trees etc. so you may need to take all your own firewood in with you.
