If you remember the "shaded seating area" that was announced (and ridiculed) to replace the Wipeout, it looks like it's going to be more than just benches and shade sails.
Concept art has been found online showing the possible outcomes for the area, and With applications for tender closing this week, construction should get under way fairly soon.
The documents inclided in the file seem to strongly suggest that option 3 is the one the park has chosen to go with and also mention that the shade sail from the old Trolls area will be used to cover the decking in the new "Ocean Parade Chill Out Zone".
