It looks like Donald Trump's hotels aren't benefiting from his omnipresence in the media the same way his campaign has, at least according to one hotel booking site.

Travel planning site Hipmunk reported that it has seen first-quarter bookings for Trump Hotels decline 59.3 percent year over year, while overall bookings through the site have generally risen during the same period.

Trump Hotels told CNBC in an email that it believes the numbers are not representative of its business and that it is pleased with its own performance.

Priceonomics, a data analytics firm that crunches Hipmunk's numbers, said that before Trump's political campaign, Trump Hotels accounted for 1.7 percent of all bookings on the site in the major cities where the hotels were located.

Priceonomics also said Hipmunk users "may skew younger and more urban than the general population."

*While the Trump Taj Mahal retains the billionaire's name, it is actually owned by Trump Entertainment Resorts, a subsidiary of Icahn Enterprises.

Trump Hotels said that it is "very pleased with the performance of Trump Hotels, and with the business we receive from our direct brand channels as well as from the larger, significant third party distribution channels with which we partner."

"The use of percentages that come from minute numbers, such as those cited, are inconsequential and do not provide a complete or accurate representation of performance," it said. "We encourage all travel planning channels to exercise caution in reporting and interpreting these figures."

Trump's campaign did not respond to CNBC's requests for comment.
