You do not need a car
Uber operates throughout Cuernavaca and Jiutepec, and it is the easiest way to move around once you are here — to dinner, into town, back to your hotel. It is reliable, cheap by most visitors' standards, and saves you parking at the hacienda.
Download the app before you travel and add a payment card that works internationally. Coverage from the airport itself is patchy, so use the bus or a booked transfer for that first leg.
Book the bus in advance
Pullman de Morelos sells tickets online, and booking ahead means you walk straight to the platform instead of queueing at the counter after a long flight.
