We go to NAS Key West yearly in late April or September have had no problems getting FHU site on the water. From November through Easter they do limit the total number of RVs allowed (approx. 400) due to space availability and use a rotation policy to be sure that FHU and boon docking sites are shared equitably. They do not take reservations and sots are filled on a "first come/first served" basis. W call before leaving to ascertain the probability of having a site available on arrival and found lots of spaces outside of snowbird season.
