Everglades National Park Camping 

I’m pretty sure you only reserve a space and not a specific site. I believe however that if you go when they are not full that there is a little bit of wiggle room as to which site you can get ;)

@@PeachyKeenes I do notice there are shade sites and some in the open. I would prefer the shade. Plus we have like 3 sites and would like to be together. Ill find out next year lol.

You might try calling them and see if they could provide you with the parameters you are looking for :)
