Arriving Tomorrow

A good friend asked if I could post a few questions on line to the community as he and his partner are scheduled to fly into Z tomorrow afternoon via Mexico city. They will be staying at the Hilton Grand Vacations (formerly Embarc) on La Ropa.

1 are planes flying into Z airport
2 if they get there will there be any taxis to take them to the club and are the roads passable. (is there an extra premium for taxis at the moment)
3 will anything be open like restaurants etc in town? We have been there twice together and only once did we eat at the HG club preferring the ambiance of local restaurants.
4 any suggestions?

Thanks and I hope this subsides soon for all of your sakes.
