First lady Michelle Obama's "spring break" working vacation with her daughters and mom to China in March 2014 cost taxpayers some $400,000, about 255 times what the average American family spends on vacation, according of military documents.

The taxpayer watchdog group Judicial Watch on Wednesday revealed airfare charges for the trip received from the U.S. Air Force that put the price at $360,000, or $11,092 an hour for the family junket.

That price does not include the tens of thousands to pay for security, lodging, transportation and communications, charges that can top well over another $100,000, according to prior trip bills.

During the trip, she made stops at the Great Wall of China, the Terracotta Warriors Museum, and the Chengdu Panda Base March 19-26.

This year they took spring break in Italy and England, another trip scrutinized for high cost and little news.

Judicial Watch has been keeping an eye on what residents of the White House spend for years and said that the Obamas have been too secretive about costs.

"Once again, we find the Obamas abusing the public trust and raiding the taxpayers' coffers for unnecessarily luxurious travel," said Judicial Watch president Tom Fitton. "The fact that it took us a full year to obtain this information about the First Lady's China junket reveals that the 'most transparent administration in history' knows that its taxpayer-financed jaunts are so excessively extravagant that it ignores open records law to keep Americans in the dark."
