First, the Constitution and case law on the matter does not say anything about giving a special higher rate to those seeking favor; it only talks about that business profiting the public official, which Trump Hotels clearly do.

Second, no, the relevant rate for any complaint is not the “regular room rate” at a Trump hotel, but rather the standard room rate of an equivalent hotel. Trump Hotels trade off the name and regularly charge 50% more than nearby high-end hotels. Obviously charging a diplomat a few thousand more per night is graft; seeking to profit at all from that diplomat’s stay, however, runs afoul of conflict of interest standards that govern the entire federal government aside from the President and Vice President. A very strong and easy case could be made that the Constitutional standard should sit somewhere between obvious graft and the administrative standard, and likely much closer to the latter.

Throw in the President Elect making business pitches both during his campaign and after the results were known, and Trump sits quite farther along the “graft” continuum than someone passively profiting from a business.

Will Republicans take the black eye of filing Articles of Impeachment against one of their own party? Probably not. But putting party above the Constitution is not exactly admirable or high-minded politics. Do you really condone and support that?
