Your observations are right. You can change of the directory name. At 
this point this use case is not documented. We should document this in 
CDK documentation.  I will open a Jira issue for this. Apart from the 
above points you have mentioned you also need to change the private IP 
in one of the Vagrantfile  to make it work.
