This is one of major issues in the Dublin area and nationally. Transfer can look easy on a map, but transport options do not always link obviously. A German style integrated timetable is needed, so you know you only ever have to wait 5-10 minutes max for a transfer during main hours (there is no one rush hour any more - people move in large numbers all day). Information on the Travel 90 option needs to be clearer - where do I tag on/off etc. On access to ports - the withdrawal of the airport 747/748 buses was a huge mistake. The private bus replacement does not accept Leap cards. The Dublin bus options also allowed for accessibility, with wheelchair space. Dublin Port access is terrible at ferry times. A taxi is the only option for door passengers
