Don't know if it's been discussed already, but I definitely think it's lame of Uni to not have Gringotts open, I can understand it not being open the first year because then people could be buying a ticket that's 45 dollars to ride Gringotts the first year it's open. But now that's been open for over a year, Uni definitely could've opened it and it would've made this event a lot more fun for me going on Gringotts with a big group of friends at midnight after walking through a house.
