For 1 night it proably doesn't matter.
The Ren is closest to the Airport (by a small distance) but it has no other benefits of its location. The Marina is on the intercoastal but as has been stated, there's a big bridge being constructed outside!
I just stayed 3 nights at the Harbour beach. Very nice. New spa which is great, refurb rooms and a great location! Good watersports activities on the beach!
