Girls, What do I do about showering?

Im a transwoman, I got invited along on a "girls trip" to go camping on the beach with a few coworkers since its our slow season. It will be at a national park I've been to before as a kid, but I also distinctly remember the showers were very exposed, like they didn't have stalls, or if they did they didn't have doors.

They all know im trans & they eagerly invited me, & i want to go, but i don't want them to feel uncomfortable. That said it'd be very unsafe for me to use the men's, and one thing I do know about salt water and sand us its not good for hair or skin.

Im not sure how to navigate this.

Well, to follow up, we went to the beach for a few days & we had fun... the only time anything was said to me. about the shower was when I was being too shy about it & they told me to get over it because we had things to do... yes there were other women there, no nobody cared... they probably didn't notice tbh.
