OMG, Kat. Live a little!
My van guy will meet you at the door of CUN and haul your tookus to Playa. If you have a lot of crap, make sure they dump you by the bus station. Hire a tricycle guy and let him do the work. He can even take ALL your bags onto the secure area of the ferry pier to wait for you. Get a refreshing drink at Senor Frogs. (Perhaps the only time you will hear me say Senor Frogs.) Take a nice boat ride. Who doesn't like a boat ride? If you are lucky, you get Ultramar with the band.
Or if you don't carry have a bigillion tons of luggage, walk out the door and grab the guy in the turquoise shirt and ask when the next Mayair leaves. Take the free ride over, buy a ticket and 15 minutes later, La Isla! $50 or less.
I did Mayair for Operation "Surprise the Missus" last month And regardless of the conventional wisdom, I took one look at the sardines queuing up for the shared vans and walked right outta the airport to 65 and the airport road. I just made to the circle when a taxi and I did the eye thing and the head gesturing. Of all people it turned out to be a guy I know who is also a paramedic. I met him a short walk down the airport road and he helped me to QUICKLY load the bags before the Federales caught us avoiding the sardine-o-van. He quoted me 120 peso to Money Bar where Operation "Surprise the Missus" entered into the full operational phase.
Seriously, for US, I can have 4 hours on one big plane and 2 hours of ground and ferry or 15 minutes of Mayair and be there. or spend 6 hours at least flying to Texas and back to CZM plus whatever waiting in Texas. And pay an extra 150 for the privilege of spending 50% more time on the big birds and rushing through the TX airports.
