I'm in Budapest and can't connect with apple email server in a hotel WiFi. My wife's iPhone and iPad is Aldo unable to connect

If you can connect to other web sites, talk to the hotel. It's possible they have blocking set up on the network that is preventing the connection. That's not uncommon in hotel Internet connections.

Regards.

It's also pretty common for hotel Internet connections to be horrendously bad with nearly non-existant suport.
