1st Time Suwannee

Good morning fam! Looking for some advice/information for my first time in the campgrounds, I tried to reserve a cabin but I’m unsure if I’ll be able to get one, I was put on the wait list, I was wondering if I get a hotel room nearby is it easy to go in and out of the park at night?

I’m just unsure if I should even get a room outside of the park or just try to get there and camp instead, what’s the bathroom/shower situation?, any information/suggestions would be greatly appreciated
