The exhibiton is till January 6th
So maybe if You could come for 1st, 2nd, 3rd or 4th January You can go there - I can pic tickets for You (: That's no problem I guess.
I would have to reserve them when they start reservations for January.
UPDATE:
The reservations for December and January will start on 19th Novemeber. I should watch out.
And You can also go there on 5th of January but without reservated tickets - and it means low chance that some tickets will be free
Lot of tourists here and only 60 persons are allowed to enter every hour.
