I really enjoyed the convention but I have a few ideas for improvements.
1st, I think there should be a roped off area for the VIP's at the parties. If they had a VIP area, the guests could come and go as they please, allowing them to still have fun and be at the parties without being crowded by overexcited girls.
2nd, I noticed a few underage girls drinking. Perhaps anyone under 18 could wear a wristband or get their hand stamped so bar staff and crew can monitor them. Or everyone over 18 get a wristband/mark so bar staff can be reassured.
3rd, To make things more fairer for the spot allocation for the Guest Encounters, maybe they should be completely raffled off so everyone who enters have a fair chance, especially those who are not as well off and can't afford to bid hundreds on one. Also, some people were having their bids sratched off without knowledge.
4th, I found there were a lack of seating during the parties. If your group were not the first of the people in, it was hard to find a group of seats together.
Lastly, more activities are needed between photoshoots, autographs and talks.
Overall, I thought everything was well planned and I look forward to ET2
