We use Uber nearly daily here. Just set my kids up with the family share plan and they can now request their own. Clara gets home from dance via Uber Black Car most nights and Alex used regular Uber X to get to Riot Fest over the weekend. In over a year of heavy use, we have only had one not so great experience. However, as it gets more popular, there are more and more suburban drivers coming into the city to be Uber drivers, which is fine, except they don't know their way around as well.
I ordered Clara some possible homecoming dresses from Bloomingdale's last week and was given a same day delivery option for $5. They were delivered by Deliv, which seems like a delivery version of Uber... regular people with cars who pick up and deliver stuff for stores. It was amazing! For just $5, delivered to my door during a delivery window I got to choose!
We haven't used AirBNB yet because my traveling husband has an obnoxious amount of hotel points. However, he and our son will be staying at one in a few weeks when they go to the University of Illinois for a campus visit (it's a game weekend, so the hotels were sold out).
