Question about Tokyo concerts :)

[septemberbabyy.livejournal.com]

Hi!

I may be going to Tokyo next month, and if the timing is right, I hope to attend one of the Digitalian concerts.
I plan to get a resale ticket from one of the idol shops along Takeshita dori in Harajuku. I've seen concert and event tickets on sale there before, so hopefully they will have them for this year's con too. Or I may buy one online, when the seating is out, whichever is more convenient and affordable.

Anyways, I have a few questions to anyone who may be able to help:
- Generally, are there any difficulties entering with a resale ticket? Especially if I don't have a fan club ID? I understand you have to produce both documents (ticket and FC ID) upon entering. I'm not a FC member. :( Can I just say it was a gift from a friend, perhaps, if I'm questioned? I'm worried about spending a large sum on a ticket and being denied entry. Also, has anyone bought tickets from the Harajuku shops before? If so, please share your experiences and tips. Is a week before the concert sufficient time to get a good ticket?

- For those confirmed going for the Tokyo concerts, may I know which dates you're going for? It would be cool if we could meet up and enter the venue together (and brave the cold and huge crowds!) :)

Thanks for reading, and I appreciate any help and advice!
