I'm pretty new to snakes, so don't quote me on this, but if I had to make more holes, I'd make them big enough so plenty of oxygen flows in, but not big enough for your snake's head to fit through.

3/16" if you use a bit. If you do use a bit use a wood working bit and rock it side to side. Don't push too hard or you can crack the plastic tub. Another way some people prefer is to use a soldering iron. Get it hot and simply push it through. Just give it enough holes so it maintains the humidity you want.

I bought some 28 quart tubs with lids from Home Depot for about $6. The plastic is flexible enough to where the plastic doesn't crack when drilling. I drilled four holes on each side, almost isn't enough because my substrate says moist all week, I prefer it to dry out a bit more. I'd go with fewer holes to start. If you get a build up of moisture / condensation you can drill more holes. Depends on your ambient humidity too, if you live in a humid climate I'd tend to drill more holes.
