During our July trip to Nice, we plan to use bus 81 travelling towards Port St John twice. We plan to use it to travel Port St John on a Wednesday morning and to travel to Baie des Fourmis stop (for dinner at Royal Riviera Hotel)sometime on Friday afternoon. We plan to walk from our hotel, The Nice Garden Hotel at 11 Rue du Congres to the bus stop. I am confused as to whether to pick the bus up at Museum/Rizzo or at Segurane. Using wwwlignesdazur.com I can't plan a journey that begins at Segurane, whereas when I start at Museum/Rizzo, I can. However, when I print an 81 route from the same site, the starting point is Seguarane. I know there have been changes to the routes and I've tried to keep abreast of them, but I'm confused.
