If you travel with kid, it is better to take train than bus.
If you have Euro pass or any Railway pass, it is cheaper to take train than renting a car.
Renting car is free to go anywhere but remember the cost of high way, parking and gas...it is not cheap.
Plan:
Day 1 - 尼斯
Day 2 尼斯 - 蒙地卡羅 - 尼斯 (one day trip, only 20mins by train) Better stay the hotel in 尼斯, because the hotel in 蒙地卡羅 is super expensive
Day 3 尼斯 - 康城 (one day trip too, because only 30mins by train)
Day 4 尼斯 - 馬賽
Day 5 馬賽 - 尼斯 - HK
If you don't go to 康城, you can go to Avignon for their cultural Fesitval which is the biggest cultural festival in Europe. A lot of street performances such as dance, music, cirque or magic. Then the plan can be:
Day 1 Nice
Day 2 Nice - Monaco - Nice
Day 3 - Nice - Marseille
Day 4 Marseille - Avignon
Day 5 Avignon - Nice
