If you can get in at all during the winter, at least fell the trees. That way if you can't get in until spring, you've got the trees cut before sap is up, meaning less time for seasoning. That is why we cut wood in the winter. Well, also there aren't the bugs and bees and hornets to contend with.
All in all it sounds like you are thinking this through and you will do fine.
