My personal experience I only ended up eating dinner throughout the con. I ended up staying 2 extra days because we were in Orlando so my family and I went to Disney and stuff, but not counting those days I probably spent over $60 for dinners only. But that’s only because the only place I ate was the hotel restaurant and those tend to be expensive. So if you plan on eating at least 2 meals a day, and neither of those meals are hotel restaurant meals, you’d probably be set with about $60 of money for food.

Buying merch all depends on how much YOU want to buy. I spent almost $100 on Starkid and Vlog Brothers stuff, but I planned ahead on buying that much. You have to decide if you want to buy a lot before going to the con, that way you have an idea. If you’re a Starkid or Nerdfighter, just go to their website and see how much things cost to get a good idea of what you’ll be buying and how much you need. I’d say $100 is enough to buy a good amount of stuff.

As for they keynotes, we don’t know how much each keynote is going to cost. If you’re a Rockstar it’ll be included, but if not expect to pay around $30 for each Keynote you want to have. 

So with merch and food, it’ll be $160, plus the unknown amount you’ll have to pay for each keynote. Assuming they’re $30 each and they’ll only have 2, you’re total cost will be about $200.
