1. Palm Islands and The World are two artificial archipelagos located off the coast of Dubai, United Arab Emirates. The Palm Islands consist of Palm Jumeirah, Palm Jebel Ali, and Palm Deira, while The World is made up of 300 man-made islands styled like a world map. The construction of the islands began in 2001 and was completed in 2008. Palm Jumeirah, the largest of the three Palm Islands, is home to numerous luxury hotels, restaurants, and residential areas, as well as a water park and a shopping mall. The World has been developed for private homes and resorts, with each island sold to private investors.

2. Since Palm Islands and The World are tourist attractions, they do not have specific working hours or a phone number. However, to visit the islands, tourists can contact a number of tour operators in Dubai who offer guided tours by boat or helicopter.

3. As there are no ticket counters at Palm Islands and The World, tourists must book their tours in advance through a tour operator in Dubai. The cost of the tour varies depending on the type of tour, the mode of transportation, and the duration of the tour. Tourists can choose between a boat tour, helicopter tour, or even a seaplane tour. Transportation to and from the departure point is usually included in the tour package.
