air-conditioned bus, fast, good roads...1. No electric sockets, and no WiFi.
2. No clear directions. In Vukovar, the bus came to the wrong platform (not the one the guy in the cashier's window knew about), and the bus also did not have the sign that we had to take exactly this bus to make the connection to Budapest. Is it so difficult to put the sign on the bus "Frankfurt, etc., connection to Budapest in Zagreb"? Is it so difficult also to print the tickets with an indication of the place of connection, such as "connection in Zagreb"?
In Zagreb, where we made the connection, again no signs, buses come with wrong signs that the drivers later changed, or without signs at all. Is it so difficult to make a sign "Connection to Budapest - platform 505"?
3. On the way from Zagreb to Budapest, the driver stopped only once, after almost four hours. Since there is no bathroom on the bus, stops need to be more frequent, such as on the way from Vukovar to Zagreb where stops were frequent, and lasted for solid 10-15 min. each.
