2018 update.
First time poster. Went to DW and WBMW over the weekend. I am F 168cm, 112kg, large bust (E) and Sz 20/22. Carry weight fsurky evenly but bigger in thighs and bum. Had no problems fitting on all rides (Tower of terror, buzz saw, green lantern and scooby doo all shut for maintenance)
Went on:
Hot wheels (front, middle and back carts)
The Claw
DoohanMotocoaster (front and middle bikes)
Giant Drop
Escape from Madagascar (middle section chairs)
Wipeout
Superman Escape (front, middle and back carts)
Arkham Asylum (front, middle and back)
DC Rivals (front section, middle section, and backwards seat)
Doomsday Destroyer
Batwing
The only real issues (comfort more than fit) were breasts and thighs on claw (seats are narrowish for bigger thighs which effects how harness sits. Had to smoosch breasts in U gap in harness.) Thighs on DC Rivals too as seats narrow and not great for those with thighs or hips. Again not an issue to secure harness more comfort (though was grateful once ride was running lol)
Hope that helps. I know i was majorly stressing before going and frequented these sites so hope this may help others.
