Worried about week long out-of-state conference

I'm going to an out-of-state conference next week from Monday through Friday and am worried that I will have a huge gain. The conference is providing breakfast, lunch, and cocktail receptions every day. Events start at 7:00 am and go to 8:00 pm some nights. I can't skip out on meals to do my own thing because I've been instructed that it's the best time to network. I'm so worried about lack of food choices and time to work out. Any advice?
