At this point I assumed it's ready for a flush and has already had tap water anyway, but yes - distilled water is best. If the choice is run the car for another day with low coolant (e.g. have to use this car to go to the store to get the distilled water), or go ahead and use tap water - use the tap water!
Also, be sure to only do this after the car is cool, preferably before start-up in the morning. You can sometimes "burp" some extra air out of the lines by squeezing the upper radiator hose. Be sure to put some water in the overflow jug beside the battery too.
