I知 planning a trip to go to Italy in end of the summer and I'm trying to figure out where is would easier to make shabbos in Rome or Venice please keep in mind meals and walking and hotel stay
Venice for sure. The whole point of the city is to walk around and enjoy the sights. All you really need is a Shabbos, Sunday in Venice or to really get everything in a long Friday and then a Shabbos, Sunday.
Also you can either stay by the hotels like the Carnival ( 2 min walk to the Jewish Ghetto) or some other fancier ones which are around a 20- 30 walk or I personally stayed by a good airbnb which was a also a 2 min walk to the Jewish Ghetto.
For meals they have a bunch of options including Chabad.
