We're going from Budapest to Vienna and were looking into train schedules and fares when I ran across "DayTrip" service at this link:[https://ondaytrip.com/landing/budapest-to-vienna?imageId=10052&ad_network=s&ad_campaign_id=353193437&ad_adgroup_id=25797054317&ad_match_type=p&ad_device=c&ad_creative_id=97806701477&ad_position=1t4&gclid=CPmOzMnN9s4CFRSEfgod8acGHQ]
Has anyone used DayTrip? What can you tell me about your experience from points A to B with them?
