Taxi may be a little higher than Uber/Lyft.
When you download the Uber App, you order the ride and it gives you an option to tip, 10%, 15%, etc. I wait until I’m into the ride or after to decide the tip. Usually, always 10%. That’s up to you.
If you haven’t, download the App, set up your account and you’ll be ready. We’ve used it all over the world.
There are men outside the port
offering Uber or Lyft. Don’t know who they are and never order through them. I say, no thanks and use my phone to order a ride share. The pickup is all along the sidewalk just as you walk outside.
The taxi, again 10-15% is what we do.
But, make sure if you take a taxi anywhere, check the price first.
