If his increased reputation encourages more people to frequent his hotels and resorts, not a problem. If his kids take over the management of his hotels and they do not have confidential information unavailable to other participants in sector, no biggie. Could they gain an advantage because Daddy is President? Sure, and that is a problem. If THAT happens, pursue the case to the full extent of the law. The MSM will happily chase that story down.
These kinds of things are extremely difficult to prove, hence conflict of interest laws.
The difference between this and Clinton, is that the Clinton foundation received donations from people who engaged with the Secretary of State. The Foundation paid for almost all of the Clinton's travel and other expenses including hefty salaries. The Clinton's net worth went from (in her own words) broke to more than a hundred million while Clinton was Secretary of State. The degree that their Foundation was able to pay the Clintons increased while she was Secretary of State.
The Clintons
did not actually receive a salary from the Foundation and had expenses paid for travel done
on the Foundation's behalf; I don't see the ethical problems with that unless you want to maintain they were skimming off the top (unlikely, since my impression is that the Foundation paid the cots directly rather than reimbursing the Clintons). And as gcomeau pointed out, any such payments' size would be independent of the level of donations the Foundation received.
Any improved ability for his business to generate wealth that does not stem from decisions made as President isn't a conflict of interest.
Offering him income to curry favor with him (as some foreign diplomats
seem to be doing already) is a conflict of interest. NTM that it gives an easy and almost impossible-to-prove channel to offer outright bribes.
