In XY it was really easy to level daycare Pokemon, raise Happiness, hatch eggs, and perform other step-based tasks, due to the infinite riding loop around Lumiose Tower, as seen here:
As you walk/ride in either direction, the camera pans around the tower, and so on until you end up where you started.
Is there a similar place in Pokemon Omega Ruby/Alpha Sapphire?
At the Battle Resort, the camera pans around as you ride around the island. You can hold 'Up' continuously as the camera swings around.
The perfect line is right up against the daycare kid, but the way to start the loop is to go to this point (just to the left of the Pokemon Center):
This way, you can hold 'up' just as the camera pans around, meaning you continue heading left whilst still holding 'up'.
It's more beneficial than in XY, as you have the daycare and the IV checker close at hand as well.
Here's a video showing the process:
There's also one in Mauville City: in the little shops on the walls, if you line up with the top-left corner in one of them and hold down the circle pad at a diagonal down-right angle it infinitely loops.
I don't think anyone else knows about it.
