Is Uber worth using?

I like to travel and I thought maybe the uber app could come in handy. Like say I ask uber to pick me up from my house and take me to the airport, so I don’t leave my car in the airport parking lot, then when I get to say London, or Paris, or Amsterdam or Tokyo etc, I’ll have uber pick me up from the airport and take me to my hotel, and then have uber take me to any sights I may want to see. I’ve never done all of this before but how hard can it be?
