BWI Shuttle Service?

[markey]

Has anyone ever used a private shuttle company to get to the airport? My daughter lives near BWI and we were considering taking a shuttle and parking at her house instead of parking on the BWI lot, this is for a 13 day trip. All our cars would require 2 trips to the airport for drop off or return which would really be a hassle especially on return. I'm not necessary looking for the cheapest, but most reliable. If not how do I find a reliable company, have found many on a search. Thanks.
