Submission timeline is today 10am till 8pm, some submit later than others. They hav to close off the area to allow contestant to prepare for their work, if some1 come in at 7pm to submit but crowds are already let inside its gonna interfere. They also hav to figure out some spacing issue since some submit ridiculously huge set pieces. If crowds are allowed in its just gonna be a huge mess on top of the current mess they r already in at the moment.

But this is actually the organizers fault, by right submission should be done the night before so that the place wont get so crowded during the day. This way, when the day start all contestant should already finalize and put on display for the crowds to view. This year they do it on the same day itself, damn crowded.

Stand there waited for 45min just so i could go in and submit mine, n because of the crowds got bump here, there everywhere. Luckily i keep everything in a box filled with foam for protection otherwise it'll probably be disintegrated already.
