famous", who often stayed and dined at luxury establishments such as the Danieli Hotel and the Caffè Florian, and continued to be a fashionable city into the early 20th century. In the 1980s, the Carnival of Venice was revived; and the city has become a major centre of international conferences and festivals, such as the prestigious Venice Biennale and the Venice Film Festival, which attract visitors from all over the world for their theatrical, cultural, cinematic, artistic, and musical productions. Today, there are numerous attractions in Venice, such as St Mark's Basilica, the Doge's Palace, the Grand Canal, and the Piazza San Marco. The Lido di Venezia is also a popular international luxury destination, attracting thousands of actors, critics, celebrities, and others in the cinematic industry. The city also relies heavily on the cruise business. The Cruise Venice Committee has estimated that cruise ship passengers spend more than 150 million euros (US$193 million) annually in the city, according to a 2015 report. Other reports, however, point out that such day-trippers spend relatively little in the few hours of their visits to the city. Venice is regarded by some as a tourist trap, and by others as a "living museum". Mitigating the effects of tourism The need to protect the city's historic environment and fragile canals, in the face of a possible loss of jobs produced by cruise tourism, has seen the Italian Transport Ministry attempt to introduce a ban on large cruise ships visiting the city. A 2013 ban would have allowed only cruise ships smaller than 40,000-gross tons to enter the Giudecca Canal and St Mark's basin. In January 2015, a regional court scrapped the ban, but some global cruise lines indicated that they would continue to respect it until a long-term solution for the protection of Venice is found. P&O Cruises removed Venice from its summer schedule; Holland America moved one of its ships from this area to Alaska; and Cunard reduced (in 2017 and further in 2018) the number of visits by its ships. As a result, the Venice Port Authority estimated an 11.4 per cent drop in cruise ships arriving in 2017 versus 2016, leading to a similar reduction in income for Venice. Having failed in its 2013 bid to ban oversized cruise ships from the Giudecca Canal, the city switched to a new strategy in mid-2017, banning the creation of any additional hotels. Currently, there
