Taking a taxi is an ideal solution after you hang out at night at Yumbo and that your accommodation is a little further (like by the lighthouse in Meloneras for example).
You will find many taxi spots in Maspalomas in main spots where you see them park one behind each other. There is one on each main entrance of Yumbo.
Or you can stop them directly from the street like anywhere else in the world.
Most drivers speak English and accept contactless card payments (including by phone such as Apple Pay).
If you speak Spanish and there is no taxi nearby, you can summer one directly to you by dialing +34 928 154 777.
And no, there is no Uber or similar service at the moment.
