沒有人規定不行,但停車位很少。見官網: Taking a car to Isla: It is not recommended to take rental car to Isla as parking on the island is very limited and it’s much more fun to walk and/or rent a golf cart. But if you must there is a car ferry service at Punta Sam just 10 minutes north of Puerto Juárez. This is your only option if you plan to bring a vehicle to Isla Mujeres. The fair includes one driver with additional costs for each passenger. Buy your tickets before boarding. The lines can be long at times, so it is best to arrive at least one hour before departure. Prices and schedule can change so please check at their website: www.maritimaislamujeres.com/en/
