Don't go to DCA or RAA- there both ripoffs. Try to find a smaller low key school that will accept a GI bill. Do not put a significant amount of money down in account anywhere. Over the last few years many have been burnt laying down thousands of $ and the school disapears.
There is a thing called pilot career foundation which will allow you to have a card with your money and swipe it as you go. That way if the school tries to run off with the money- they won't have access to your account.
Many schools expecially in the Orlando area, have been notorious for ripping off student pilots with CFI's milking students for time, retaking stage checks over and over, making false promises and flat out stealing.
Heed my warning.
