We're planning on touring Genoa and Italian Riveria in mid to late May 2014. I've discovered that the Cannes Film Fest and the Monte Carlo Gran Prix are also about that time. Should we expect spillover from those two well known events to have an impact on hotel availability and larger crowds near Genoa and the Portofino/Santa Maria Lig. area?
If so, would it be worth our while to tour that area in early May instead?
