Solution: Seaside Holiday
Answer: HALONG BAY

Written by Zhao Yan

Teams are provided with 9 clues and 9 coastal locations on a map, so it is natural to match them one-to-one.

The first part of each clue describes a certain location. Teams will soon find that these locations do not match those indicated on the map; in fact, some, such as Manchester, do not even lie next to the sea.

Teams will now need to figure out how to use the remaining parts of the clues. The aha is to realise that each clue describes a city named after the location, but with a sea-related suffix.

A starting point could be to google some of the more concrete ones: la Casa delle Farfalle will point one towards Milano Marittima, while a 2016 film containing Manchester suggests Manchester-by-the-sea. These can be confirmed by matching the locations on the map.

To identify the remaining clues, teams can Google the locations with an added "at/by/on the sea", or look up the Wikipedia disambiguation pages for the locations, which will list other locations of the same name (including those with the sea suffixes). Many of the descriptions are excerpts from the Wikipedia pages of the locations, which should help. To help identify cities in countries where English is not the first language, clues contain words in the local language, which suggest searching for "on the sea" in the corresponding language.

The complete set of clues and answers is given below. Clues are alpha-ordered by city name.

Finally, teams need to identify each city on the map and index into the city name using the number of stars. Rearranging by the order given in the map gives the final answer, HALONG BAY.

Author's notes

The inspiration for this puzzle is a popular nickname for Halong Bay in Chinese: 海上桂林 (Guilin on the sea). The original version of the puzzle required teams to infer the final answer after extracting GUILIN, but that idea was discarded as the English moniker is less well known and potentially ambiguous.
