Bookings at Trump hotels in Washington, DC, and New York — which plunged during Donald Trump’s presidential campaign — have spiked since his victory.

The Trump International Hotel Washington, DC, just blocks from the White House, has seen a 20 percent increase in reservations and is sold out for Inauguration Day weekend in January.

“Wow. Demand is definitely up,” said Jack Ezon, president of Manhattan-based travel agency Ovation Vacations. “I didn’t expect it to happen so quickly.”

Bookings at the Trump International Hotel & Tower New York are up 18 percent since Election Day, and there has been a 15 percent rise at the Trump Soho New York, Ezon told The Post.

A check on the Expedia travel site Thursday showed the Trump New York was sold out for Friday night, while similarly priced hotels, like The Plaza and The Mark, had vacancies. Rooms were available at the Trump Soho for about $500.

But reservations at other Trump-branded hotel and resorts remained virtually unchanged.
