You'll need to decide whether you want it 'bright' (or racked, i.e., free of sediment), in which case it will be drinkable immediately after travelling but won't stay good for more than 2-3 days; or on sediment (unracked), in which case it will need 12-24 hours to settle after travelling but will last much longer (over a week if in a cool place and not disturbed).
Most suppliers of polypins (20 litres) or minipins (10 litres) fill them with bright beer so that the consumer has nothing to worry about.
