Bolt charges from airport to hotel to train station

If anyone has an active Bolt account and could look up a fare without actually going through with the reservation I'd really appreciate it if you could let me know how much it would cost to take Bolt from the airport to the Michelangelo Grand Hotel and from the Hotel to the main train station. There are 4 of us coming in July. I just want to see how it would compare to the hotel ordering something for us and I'm assuming if I uploaded the app it wouldn't be active until we landed in Prague. Do you add a tip to the total that you prepay with your credit card? What's the expected tip amount? Is it cheaper than an Uber? Is it more expensive at night? We might need to catch one from the Tavern U Krale Brabantskeho by the castle to our hotel. Thanks a lot for your help.
