Little Tybee Island

I need the Sand and Sea. I’m a tent camper. I know Tybee beaches are very crowded, but I’ve heard the Little Tybee Island, is not so crazy as it is only accessible by boat.
I’ve been on TheDyrt of course and checked that out. Not a big hotspot (yay!!!) so only a couple reviews. Can anyone tell me more about this option? Thanks in advance!
