Agree with the above. Irrespective of tariffs there will be a degree of drop-off in leisure demand simply through people avoiding or actively boycotting the USA. I know people that have said they wouldn’t go at the moment, I’m sure many others do. Stories of people being detained and badly treated either wrongfully or due to minor errors won’t be going unnoticed, in fact the UK’s travel advice has subtly changed in that respect. I’m aware some countries have gone further. I’d imagine people with less ‘European’ sounding names may have greater nervousness.
There is a world in which the opportunistic seize on a collapsing dollar to go shopping in NY or over to see Mickey. But that assumes status quo on general safety, it’s not beyond possibility there could be civil disturbance.
