As part of our Italy trip, my husband and I will be based in Milan for a long week. Plan is to take many train day trips out (Como, Parma, etc.) Is it feasible to train down to Monacco, do an hour walking tour, say, and lunch and then back in one day? We enjoy seeing the countryside from trains and simply want a brief experience on the Riviera. On our last trip to Italy two years ago we visited an amazing amount of cities and villages for an amazing experience but were on a dead run the whole 20 days. This time around, I'm going for a broader picture and more relaxing adventure. So, again, is Milan to Monacco for lunch and then back simply doable and too much to accomplish in one day, or could it be an easy, fun experience? Your valuable input will be much appreciated!
