It depends. Instead of calling out specific numbers, I'll generalize. First is traveling costs. Airfare, train, bus or car. Don't forget you need to eat when traveling, and there is always somebfee or another to pay. Buy a round trip ticket. It sucks to be broke and unable to get home.
Room costs. Whatever the hotel charges for the room. Added to the quoted rate are taxes and fees. Figure 20 percent more than quoted rate. If you don't have a credit card, hotel will also want a damage deposit, or put a hold on your debit card for additional money. This is typically one additional nights costs. You do get the money back (unless you do damage the room) but not until you check out. So that money isn't available until you get home. Cost of convention membership. Unless you prepaid, the con needs that money and won't let you in free. Food. Budget for at least one restaurant meal per day. If the hotel has a breakfast buffet with the room, that is probably the best deal for food. Your other meals can be a mcburger or something like that. If the room has a mini fridge, get a loaf of bread, sandwich fixings, and inexpensive beverages at local store. Hotel soda machine is the most expensive way to buy a coke. Booze is even more expensive at the hotel bar. Bring money to buy stuff in the dealers room. And bring money for incidentals. Taxi fare to and from train station, tips for the bellhop and the maid that cleans your room. ( Dollar per bag for bellhop, dollar per day per person for the maid. More if you ask for extras or left the room a mess. Pro tip. If you left the room a mess, twenty bucks left for the maid is way less expensive than the hotel taking the entire damage deposit.). If you smoke in your hotel room, the hotel will whack you for a couple hundred bucks for special cleaning.
Plus money for emergency. Keep back some for the unexpected.
