trip from johns hopkins, baltimore to Disney

We are taking a trip to Disney for our grandkids. We'll be in our 38' class A/ no toad. We have an appointment at Johns Hopkins in Baltimore as part of the trip. Any suggestions for travel from downtown Baltimore to Disney? Would like to avoid DC if possible as we will be in that area on Friday shortly early afternoon. Any possible routing would be appreciated. Thanks

There is a way south without going through Washington, if you got sometime on your hands and in no hurry. Other than that, I'm afraid your going to have to contend with the southern beltway around, 495. Maryland 3/301/207 runs all the way from Balitmore to connect with I95. Good luck.
