Got tickets but still u must look for a suitable place.
Because if you are going to shoot fireworks which I think the answer is quite obvious. You need to find space for your tripod, dun have get 1. Then you should have a remote control shutter too.
Shooting with tripod at your seat will be quite useless, I think everyone will be standing up when the clock strikes 12 and your shot will be blocked. Look for a clear spot to shoot.
