Asking for assistance on ADS Convention travel, please

When I depart the ADS Gettysburg Convention, I will be flying out of BWI.  I’m not clear on what transportation options there are, for me to be able to get to BWI in a cost effective, no hassle mode (I DESPISE shuttle transportation that takes twice as long as it should because the company stopped at every pig path on the way to pick up and drop off).  If you have input/advice – I’d be appreciative for your feedback.

Thanks,
