What is the rationale for requiring White House tours be scheduled through a member of Congress? was recently closed as being off topic while Why are balloons prohibited at Amsterdam Schiphol? is apparently on-topic.
I think that's silly. If one is on topic they should both on topic and conversely if one is off topic they should both be off topic imho.
I mentioned the balloons question in the white house question and was told "well at least the balloons question is about airports". The white house question is about a tourist destination. That's what airports are. Tourists go to the airport and then go elsewhere.
This isn't some "why is the sky blue?" type question. That has nothing to do with travel because the sky isn't some specific tourist destination. But the white house is.
If questions about tourism aren't travel related then why not close every question in the https://travel.stackexchange.com/questions/tagged/tours category?
