It would be a far too expensive, laborious and frankly pointless task to retheme Battle Galleons, Sharkbait Reef and Marauders Mayhem which are some of the best themed attractions on park (not saying much really) even if the area itself is tired.
SW8 needs to be pirate themed in some way but done with a twist to give Mutiny Bay more depth to its presently shallow and hackneyed 'brown paint and skull and crossbones' pirate theme.
But alas, it's Merlin, obsessed with their USP's and IP's so the whole creative approach will be marketing led and we will likely end up with a theme clashing standalone attraction like Galactica, Derren Brown, Gruffalo etc.
They really only care about getting people through the gates.
