I have a couple of theories on "Casey code". Personally, I believe that all the references to Sawgrass have to do with this place - Sawgrass Plantation.

This has been mentioned before about another Sawgrass. It also has a road that matches the tat Casey had done.
Sawgrass Plantation
This is somewhat close to the airport and a large shopping mall
There is a Belle Vida Rd within this community.
Sawgrass Plantation 12649 Sawgrass Plantation Blvd. Orlando, FL 32824
According to a review that was written on a open forum for people looking to purchase homes this Sawgrass is a family oriented neighborhood, across the street from one of the largest outlet malls in the US, Walmart, Super Target, all the major eateries, major expressways, Panther Stadium, etc. Close to the airport.
This is the site of MI Homes that does sales within this Sawgrass.[There are a lot of realty companies that deal with these homes and some are for rent as well as for sale.]

Going with the tat theory there is another road in Orland with the same name. Belle Vida Blvd. [this was also mentined early in a thread] I was looking for address that Casey may have been to and found that Belle Vida Blvd in Orlando is very close to the Fusion place.

Casey has said numerous times she is close
Casey does not seem to travel to far away from home. About 10-12 miles if you plug all of her known friends and party places into a map program. This place would fall within that range
