Guinness storehouse time recommendations

Hi all!

Me and my friends are visiting Dublin for St. Patrick's day and we are planning on visiting the Guinness storehouse during our trip. We plan on taking the academy experience.

Do you recommend we go to the Guinness storehouse on St. Patricks (on the 17th) after the parade or to go after St. Patricks in general (e.g. on the 19th)?

Replies much appreciated!
