Hey Keem,
Just a suggestion. I actually sent an "in the update" email to Georgetown after receiving an invite from GWU, telling them I was going to be in the area to interview at another school. I asked my prehealth advisor about it, and she said that some schools would consider the email, and the worse thing that could happen was that the school could say no (maybe it would be followed by a rejection). I worded mine very carefully not to come off demanding or presumptuous.
I never got a direct response to the email but I was sent an interview invite less than a week after I was considered "complete" which I have not seen for anyone else on this board (complete 8/6, invite 8/12). I am convinced that my email actually did have an effect, and I was able to schedule my interview at Gtown the day after my GWU invite.
Again, the email would probably only work if you are competitive to get an interview invite anyway. If money is really a concern, you can definitely try it.
I want to emphasize that this was my personal experience, and if you get a rejection because of it, I cannot be held responsible. 🙂
