Married SNA's receive follow-on orders to Whiting probably because the Navy doesn't want to pay for an extra PCS move (with dependent) to Corpus. Instead the move to Pensacola is considered a permanent one for married SNA's as opposed to their unmarried counterparts who generally sent to Corpus for primary. With this in mind, my wife and I found a place in Milton 35 minutes from NASP and 15 to Whiting.
IFS is a different story. The three locations are Mobile, Bay Minette, and Milton. Although I've heard that Skywarrior is moving to P'cola, which will be nice. Nevertheless, married SNA's are not guaranteed a certain location.
