go see son in Georgia in Army

I m a hard working mother of 6 and really hate to even ask for help. That is not like me. My son left for the Army June 5. He is at Fort Benning Georgia for training.  He is having a family weekend the end of August and really need to go.  His great grandpa passed away on the Fourth of July and my son was really close to him.  I was able to tell him about it but would really love to go see my son. Please help in any way thanks and God bless. Anything will help. Just cost for a room and have to rent car mine will not make it down there.
