CIS-2016 in St. Petersburg.

Guys, what about a big gathering on the 30th?
Is anything large-scale planned?
Also, a question about food: if we bring meat for a barbecue to cook on a grill, is there anywhere to store it? Or only in the room's refrigerator?

People from St. Petersburg, does anyone have at least a rough idea of what the traffic will be like on the 30th? We're planning to drive from Moscow, but we haven't decided on the departure time yet. We suspect that the 30th will have terrible traffic, so we'd like to hear what the best time would be to arrive in St. Petersburg to either avoid the traffic or at least minimize the time spent in it. We'll plan our departure time from Moscow based on that.
Roma suggested that it would take about 3 hours to drive, but we're interested in the opinions of others.

P.S. We can arrive in St. Petersburg at 6 a.m., but is that necessary? Or we can arrive at 2-3 p.m. The main thing is to reduce the time spent in traffic, as driving will already take a lot of hours, and traffic will just make it worse.
