Bus service to/from DTD and any resort is always pretty slow.
Bus service from DTD to BWI is very slow. Depending on where you get on the bus at DTD there may be another stop there, then depending on the time they may stop at a water park, then the bus goes to Swan, then Dolphin, then YC, then BC before BWI. I just get off at the Swan and walk back to BWI-it isn't too far and MUCH quicker.
