I wasn't there, but it sounds like:
1. They screwed up logistics last year in the move to a new location which really messed up the event. Sounds like some of the problems were avoidable.
2. They have apologized for the problems.
3. They have put a plan together to address them.
What else do you want them to do? Personally, I would wait a year and see if things are improved before going back, but it seems like they are making an attempt to fix what happened last year.
