Yes, there is a bus going from Leiden. It well marked on the right side of the station.https://keukenhof.nl/en/ov/

Uber is not the only app for taxi rides, FreeNow and Bolt are some others you can use. Those might give you also a chance for a ride.

Depending on your starting time, I would do the shopping streets, ea Lijnbaan, first, those are more less deserted at night. End at Markthal for a bite and maybe getting some snacks.

Take a Canal cruise, or visit the Big Museums around Museum Square. The Rijksmuseum for the Nightwatch or The Van Gogh Museum. Next to the Gogh is the City Museum for modern art. Anne Frank house is also an option. All the musea are easily reached by public transport. Reservations for the Musea are recommended especially the Anne Frank house.

Wich time of the year are you going, some excursions are time restricted.

Thanks everyone for the input. I'll save the coupon for a later date. For the next voyage I am covered by a beverage package.

Just a simple question. Can it be used for a Milkshake?

Another suggestion: The Hague: Mauritshuis, or Haarlem: Teylers Museum.

I am familiar with the location, not the hotel. Location wise it is perfect. Close to Public Transport, Jordaan district and the Museum district is just a couple of stops away. I have been in another Westcord hotel, they had a clean pleasant vibe.
