He was there 2 nights. He arrived in Moscow on the 8th, lots of events and meetings, Aras Agalarov birthday party until late on the 8th/early 9th, slept in the Ritz, another very busy day, ending with pageant and after party going into the morning. After that I'm not sure.
So if he flew out of Moscow at 3 or 4 am on the 10th (on Ruffin's private jet?) then maybe he didn't sleep in the Ritz a second night. But this all seems unlikely. It would be good to nail down when he flew back.
So he tweeted at 9:44 pm on the 10th that he just got back from Moscow. Assume 10 hour flight time so maybe he left Moscow around 11:00 am U.S. eastern time on the 10th. This would be 7pm Moscow time. That's a sizable gap.
