Meeting info for fans going to Yokohama concert on 9/5 or 10/5

[Hatix]

I wanted to make a topic for all the people who are going to the Yokohama concert on the 9th or the 10th of May. Me and maneayu will be going to both concerts. But we definitely want to meet up with the other AHS members who are going to these concerts.
So who are coming to the Yokohama concert for the 9th or the 10th of May. The ones that I know of from the other thread are:
eddi818, Blasterion and ayu1m. Anybody else? And to which one of the concerts are you going? and in which hotel are you staying?

Up until now:
Hatix: 9th & 10th (Oak Hotel, Ueno)
Maneayu: 9th & 10th (Ryokan Kangetsu, Chodoricho)
eddi818: 9th (K's House, Ueno)
ayu1m (+friends): 9th & 10th (maybe, still need tickets) (Shinjuku Washington Hotel & Andon Ryokan, Ueno)
kel64: 10th (Tokyo International Hostel)
Joeyoh: 10th (Keio Plaza, Shinjuku)
Blasterion (+sister): 9th (Andon Ryoan, Ueno)

So what am I suggesting that we do. I have this planned for the 9th (on the 10th I'm visiting the imperial palace at noon, so we are later in yokohama).
Anyway, what I suggest: go to Yokohama around noon or a bit before noon, and do some sightseeing, go eat in the Ramen Museum before the concert. Then go to the concert, and meet up again afterwards to go back to Tokyo together, and go karaoke with everyone (in Shibuya for example). We could do something similar on the 10th also, but I don't know what everyone is doing or going.

(I'll update the top post with new info)


Our schedule for May 9th (I take time very wide):
11h30-12h: Meet in front of Tokyo Station, watch for my AHS-sign
12h: Take the shinkansen to Yokohama (for those without japan rail pass: 1320yen)
12h30: Minato Mirai 21
13h30: Yokohama China Town
15h30: arrive at Ramen Museum
16h00: Eat at Ramen Museum
17h30: Concert (doors)
18h30: Concert start
21h: Concert end, take shinkansen back to Tokyo, and go to Shibuya
21h30: go to karaoke
23h30: get our last train back to our hotels ;p

Schedule for May 10th:
10h Imperial Palace (reserved in advance)
Budokan, Yasukuni Shrine
13h: free until the concert, go early for buying concert goods?
17h30: Concert (doors)
18h30: Concert start
21h: Concert end, take shinkansen back to Tokyo, and go to Shibuya
21h30: go to karaoke (again, or something else?)
23h30: get our last train back to our hotels ;p

so you can join in any time you like, but it would be fun if we could spend the whole day as a big/small group. suggestions are welcome of course (but the imperial palace visit can't be changed, that's already reserved, there are still available places, so you can still join: http://sankan.kunaicho.go.jp/english/index.html )
I will also be looking up all other trains/subways to take, so we know where to go and don't get lost

Some extra info:
- there are coin lockers in Yokohama arena on the 1st and 2nd floor
