Other than that my only other big question would be how much earlier than the event start should I try and line up for? Of course since it's my first time I'm open to any advice at all realy.
As there is a trial release of Touhou, I assume there will be more crowed. People line up as early as 6 in the morning. I remember when I was regular visitor, I lined up at 8:00 and was outside and downstairs before the Big Site. Depends on what your goal is. Lining up between 7 or 8 in the morning is cool. Earlier if you're going for the popular circles and want to spend your time more effectively.
Other than that, some basic advice:
- Bring along a cap or something to cover your head. On a sunny day, if you're lined up outside, it can be dangerous to stay in the sun exposed for longer periods.
- Bring along bottle of water ( 1 litre at least )
- Bring some basic snacks along to keep your energy levels high. Like fruit, onigiri and such. Buy them the day before.
Also remember to have fun. Don't worry too much about the whole thing. Like Forza said, it isn't comiket so there is crowed but it isn't crazy and annoying.
EditHere is a map of all the circles and their spaces.
