My mom's co-worker Angel works as a tour guide in DC during the school spring months. She's done it for years as well. My wife mentioned about what does it take to visit the White House. Angel had done tours there as well with schools so she knew how it worked. She said it was different now because under Obama, the demand to got the White House was so large, that it was about a two year waiting list.
It's apparently only a few months for the White House under Trump. Though to be fair to the Liar-in-Chief, he would have more popularity at the White House if the grand mansion was located about two miles from Mississippi trailer parks than a city like DC.
