In light of yesterday's 's**thole countries' remark by The Great National Embarrassment, one may wonder if American tourists are getting stick from the locals about these presidential remarks (and the president generally).
For the record, I took four trips abroad last year (Barcelona, Sofia, Vilnius and London) and did not get one bit of negativity from the locals - no denunciations, no physical attacks, no refusals of service, nothing. My trips went quite normally; in fact no one with whom I came into contact raised the issue of Trump at all.
Now I have more trips scheduled for this year (Paris, Bucharest, Tallinn; also London once my regular hotel becomes available from British Airways Holidays) and I'm not expecting any stick from the locals on these trips either. In my 40 years' experience in travel aboard I find if you give the local language a go, show respect for the locals, and stay out of overtly political milieux you shouldn't have any trouble.
