The most economical and simple way to get from Morelia Airport (MLM) to the hotel when arriving is via taxi. Taxis are about $500 Mexican pesos which is give or take $25 USD. Before you exit the Morelia Airport you will see a Taxi Kiosk. This is where you will get a ticket to board the taxi. You don't pay here. You will be asked where you are going. Have your hotel address ready and either say or write the word "AUTOPISTA" (toll road) so that they know to use this road to the city. The autopista is the faster option to get into Morelia.
Once you have this ticket, you can get in the taxi line outside. This line is typically short and goes fast. Hand your ticket to your driver. You will pay your driver once you arrive to the hotel. The drive should take about 30minutes. More if there's traffic.
It's best if you have Mexican pesos at arrival to pay for the taxi. But you can also exchange USD cash to MXN cash at the airport as well as use the ATM at the airport.

Another option is a private shuttle which costs about $2,000 Mexican pesos or about $100 USD. If you're interested in this option please contact Mariana or Thomas so that we can set this up with our wedding planner.
Lastly, you can also inquire with your hotel, they might be able to offer airport pick up.
Morelia is a small city and is very walkable. When not walking, taxis and uber are fast and easy options. We don't see the need for a rental vehicle, but if you are planning to explore and or extend your stay you can find info here: https://themoreliaairport.com/car-rentals/
