I think, if it's at all possible, it should be made easier to get into the Dungeons. People can be quite rude when they want to be by sort of stealing your spot which discourages you from even trying to get in. I've been standing on the same spot for five minutes and somehow keep losing my position to someone else at the very last second and it's not very fun that way.
Well I think that is all going to change with the Grouping feature that is coming up with the Grizzleheim update. It can have up to 4 people to group with and that way if your in a group you wont lose a spot. The only question I have is would it be possible to use grouping for school quests also or are those still a single quest?
