CIS-2016 in St. Petersburg.

Vigo1402: I didn't quite understand the meal plan, could you please explain? A ruble is the daily cost for breakfast, lunch, and dinner as a package. But how much would it cost separately? For example, why pay for breakfast if you don't come in the morning, or for dinner when you might have a barbecue or go out in the city? But lunch, for example, could be an option, but not every day. Where can I see the prices separately?
