Sorry but are you just not reading the information already given, why are you asking me when she went to Little St James?
Again the applicability of Federal law is
not "down to where" Andrew stayed or had encounters, Federal law already covers the entire United States, it doesn't matter where in the United States someone is, the Federal Age of consent pertains to crossing state lines... that's where Federal law comes in instead of state law.
So even if the age of consent is 16 in both locations if you cross from one state to another to have sex then it's Federal law that applies.
What’s legal and what’s not?

If you think otherwise and are going to carry on claiming "it's down to where" then provide a source that shows how it can simply apply to a local situation and superseded state/local law. It doesn't matter where in the US, it matters that state lines are crossed, otherwise local/state law applies not Federal.
