There are 5 of us in the family. Been getting quotes from local tour operators. If we want to be picked up from Monaco, visit Cannes, Antibes, St Paul De Vence and Eze, it's about 480-500 Euros for a full day tour. So I am thinking, is it possible to hire a taxi once we dock in Monaco, and have the taxi drivers take us to these places? Would the 5 of us fit into 1 cab?

I know Cannes is on the train line, so might go with plan B to take train to Cannes from Monaco, visit Cannes, Antibes, and maybe Nice old town? They are all on the train line. But I have heard St Paul De Vence is really nice. Eze is hard to get to by train/bus if you want to DIY. Could anyone who has hired a tour company or have DIY the region, please share their experience. Thanks.
