We have started using "Seacrest, FL" as our mailing address instead of Panama City Beach. It is not because I'm a snob. There is actually a street in Carillon with a similar name as our street (different counties, but same zip code) and our mail, FedEx, UPS keep getting misdirected. Since we started using "Seacrest" we haven't had any problems. As long as the zip code is correct, the city name doesn't really matter and it is much less confusing for everyone.
We started using Seacrest as our mailing address too. I have heard from others that the post office doesn't like it, but we are getting our mail.
