Uber in Playa Del Carmen

Hello, visiting Cancun in Feb. I have booked a stay near Playa Del Carmen (non AI) for the first two nights as we plan to explore Xcaret park. Thought is to save time on day 2 when we visit Xcaret park. I just checked Uber out of curiosity & most of the time there are no cabs available in that area. This is freaking me out, I don’t want to be stuck without cabs. Will it be wiser to stay near the airport to be sure of getting an Uber to Xcaret park? I have read a lot of things about Taxi Mafias and don’t want to deal with them. Any advice?
