Booking.com is expected to announce Wednesday at a conference in Europe that it is debuting an offering in 10 European and Middle Eastern cities that enables customers to book tours and attractions on a standalone basis without having first to book a hotel room.

The pilot program, available in Amsterdam, London, Paris, Berlin, Rome, Barcelona, Vienna, Prague, Edinburgh, and Dubai, is available on city pages on the site, and offers everything from a skip-the-line ticket to Madame Tussauds Amsterdam to museum tours, and hop-on-hop-off bus and boat tours. The listings are available in 43 languages.
