WiFi (which for today’s standard should be as easy as nothing) was a big problem. Initially, last name and room number, should give me access, but no. After initial access, I was presented by a mandatory subscription to a Hilton log-in, which stranded because I did not have a US phone number. And the reception could not help, because this was way above their possibility to assist.
Initially, small problems can «destroy» tjue impression. Easy access wifi is important for international customers.
