My 'send' button does not work either ;) so, can only talk with you here..
I'm afraid that we may have to cancel the activity on this Sunday (Nov 9) due to too few people registered. Would you like to shift your registration to the next Sunday, or any Sunday within this month? If so, pls tell me your preferred date, and I can reserve it for you.
About the traffic, get prepared that it may take 2 hours for coming here as you are traveling from the very west of Shenzhen to the very east, and there's no subway connection. But I'll look for you the best way and let you know later.
