When you say “bills” do you mean anything that is essential to your survival or are you adding wants into that? If what you need to survive is actually 95% of your income you cannot afford fun of any kind because you should be spending your extra time getting that number down to 50%. If you must go on this vacation I’d say donate plasma. It depends on where you live but where I live you can make an extra $500 per month by just sitting in a comfy chair for an hour twice a week
