I suppose they do not.
We have used Uber in countries where we do not speak the local language e.g Poland. Entering just the locations worked fine for uns.
We recently used GRAB (similar to Uber) in Bangkok and it also worked perfectly for us, never got lost 🙂
I have just checked the availability and might give it try after out Jan Infinity cruise. The actual price is approx. 60USD and availability looks good. Would just be keen to get some live experiences with UBER.
