"In PVR" ?????

Uber is not allowed to pick up at PVR (the airport code). If one is very familiar with PVR property and surroundings, an Uber can pick you up after exiting PVR property, which is Federal land, either by crossing vía a steep bridge the busy main N/S road or walking to a nearby hotel. Then you set up your Uber (cannot do in advance) and wait for Uber to arrive. Uber knows the zones and fares, so they may come in a few pesos only cheaper from the airport area. By the time you walked then waited you could be 20-30 minutes down the road to your destination.

Hence, Federal taxis only from PVR.

Shuttles such as the OP first asked about can enter, they have to file with Federal authorities at the latest 24 hours before intended pickup to receive permission.

Puerto Vallarta certainly has reliable Ubers I use them all the time. Is that what you meant, "in Puerto Vallarta" not "in PVR" ?

Mismaloya probably has Uber availability, hopefully the OP can report back if Uber is used.
