if want to save money, take the long distance bus inside the airport. Get another grab/uber once in the Johor bus station.

Pls call the uber driver to alert them on your destination....driver will appreciate that. Prepare to top up additional fare because driver need to come back empty car from Johor.

Otherwise driver may ask you to get down the car after loading your luggage in the car is like no very nice.

Just my 1 cent suggestion from driver point of view.
