Depends on what your starting levels are on your DD - assuming they are lvl 1, I'd say it is impossible, unless you manage to do what the above anon described. DD are a bit hard to grind together, since there aren't many maps suitable for grinding where multiple DD can be used at same time. 1-5 Below HQ lvl 80 is pretty much the only map for that right now, but the exp gain is rather low, and it is not good when above HQ lvl 80.

However, the event is 2 weeks long - it is not like you have to have your fleet completely ready when the event starts, you even have some time for grinding during the event. Usually, 2-3 days are enough to clear all event maps, unless there will be something like summer E-6. Some people even manage to clear all event maps in just a single day. Of course, rare drop farming will take time unless you get lucky, but that is more like a bonus anyway.
