I am in a similar situation. We have not been since 2006 and are going in July. The biggest thing I have learned about is definitely Fast Pass plus. We are staying off property so I thought we could not get them but have since learned the difference is on site can make them 60 days in advance while I can only make them 30 days in advance (still better than not being able to do it at all). One key is knowing fast pass plus starts at midnight. Another thing I have learned is using the mydisneyexperience app or site you can make your dining reservations at 6am eastern 180 days in advance. You don't have to wait for the phone lines at 7am. One other thing I am thinking about is the memory maker.
