That would be a great answer to continue from. Would you come for the Biennale specifically? Do you care greatly about sustainability? Would you enjoy yourself more in a different gorgeous city without the mass-tourism problem if that meant you would feel more welcome? Is there a way you can visit Venice without contributing to the issue as much? Off-season perhaps?

Venice is unique, but there are a lot of gorgeous places in the region, from Verona to Trieste.
