In the early bow season I field dress the deer immediately (same year round) and as soon as I get to the first store I buy about 3-4 bags of ice and put them into the body cavity for the 30 minute trip home. I have the leisure to take it into the basement where I skin it and quarter it imediately then pack it on ice in a cooler of ice for a day or two. Then I'll bone it and seam it all out for packaging. Dont worry about the (draining) You'll be surprised at how much it will drain in the cooler and if you feel it needs more then after taking it out of the freezer and thawed soak it over night in water. Naturally if it's cold out you can hang it for a couple of days but only if the temps dont exceed 45 degrees.
