It was easy and the train is great fun. Once up at San Luca, I recommend spending at least three hours to enjoy the cathedral (Pay the 3 euro for the sky experience), relax in the parklands and get some lunch in the Vita a San Luca restaurant there (great pizza). Then, the vouchers they provide for after the trenino are a great afternoon snack.

A little chaotic getting on the train on a busy day but once you’re off it’s magical and fun. The basilica is really beautiful and the views are astounding on a good day. If it’s clear it’s 100% worth it to pay extra at the top to climb to the dome viewing deck. The free lunch tickets are great but they may not fill you up too much! Relax, enjoy and have a laugh at the buffoons who ran all the way up the portico.

Train with its audioguide was great. Also, tasting the local pastry was quite a nice thing (warning though: each person only gets one type of pastry), however the other part of the food tasting (the "main dish") was quite dissapointing (Bologna is world famous for its cuisine, however we were literally given just one type of fast food). My advice: book the train to the basilica separately and then explore Bologna's cuisine on your own.
