From Luxury Travel Magazine some key findings from the 2020 Luxe Report*:
I would agree with this survey but two of my favorites are not listed and that would be New York City and Sydney. What I would mention is all of these cities are very easy to get around as far as transportation. They offer terrific cuisine, amazing architecture, tremendous historical significance, and vibrant nightlife. You could combine at least two of these into one trip.
