That was covered in one of your previous posts:

You'd need to travel to either Naples or Sorrento to catch a boat to Capri in March as it's off-season for the island and much of the coast.
If there's anything that might fall under the definition of a tourist trap on Capri, it's the Blue Grotto. Ability to enter the cavern is dependent on weather/sea activity so I wouldn't put it on the must-do list.
