PilotEdge’s CAT 11 Rating had me doing my first coastline flying (dodging Restricted Airspace and entering a Bravo, too!) and I enjoyed it!
If you ever want to take your flying / real-world communication skills to the next level, I highly recommend PilotEdge. It is a paid service, but it’s really immersive. Flying on a network with others, and communicating with ATC is way cool.
While not “coastline” flying, I did fly the TN river from 8A1 to KAPT.
