Caller has a generation 1 Echo and a gen 2 Echo Dot for his dad. But he can't get it to log in when they bring it travelling. Leo says that it can largely depend on joining the WiFi of a captive portal network. Leo says a Travel router like the Tiny Hardware firewall would be ideal. They have one called the Trek Travel Router. He can then log into the phone. Just plug the router into the wall, the router will then give you a website to log into.
