Besides hotels and restaurants, services to tourism have required additional infrastructure, including: airports, roads, sewage treatment plants, landfills, electricity supply and telephones. Much of the profit from tourism is earned by corporations outside of the Caribbean since, "two-thirds of the hotel rooms in the region are foreign owned, and the tour companies who arrange visitor's activities are often foreign owned". The more luxurious the accommodations, the more likely that profits are made by foreign firms. Further, many resorts are all-inclusive, and vacationers of these resorts rarely eat out at locally owned restaurants, rent water sports gear from local entrepreneurs, or arrange island tours with local taxis. Most of the food served at hotels is imported, locally grown fruit, such as breadfruit, bananas, mangos, and citrus is rarely served. Only about 30% of money spent by foreign visitors remains in the Caribbean, the rest is retained by overseas firms. Tourism development has driven up the cost of food and land, land which may be purchased for hotel, marina, and other tourist facility development by companies able to afford the price. If they have a home, they may be pushed out of their residence due to the high cost of living or hotel construction. Tourist attraction of the region are those generally associated with a maritime tropical climate: Scuba diving and snorkeling on coral reefs, cruises, sailing, and game fishing at sea. On land; golf, botanical gardens, parks, limestone caves, wildlife reserves, hiking, cycling and horseback riding. Cultural attractions include Carnival, steel bands, reggae and cricket. Due to the dispersal of the islands, helicopter or aeroplane tours are popular. Specific to this tropical region are tours of historic colonial plantation houses, sugar mills and rum distilleries. Caribbean cuisine is a fusion of cooking styles, goat stew being the signature dish of several islands. Marijuana has developed in importance since the 19th century, becoming a significant part of Jamaican culture. A large number of the visitors are honeymooners or people who come to the islands for a destination wedding. Tour operators use oblique references to sex tourism to attract customers. The recent studies shows that some Caribbean islands, like Cuba, Hispaniola, Jamaica, and Puerto Rico has a huge potential for mountaineering activity, however, it is not utilized properly. Some historians and cultural anthropologists say the changes to the islands to support tourism have negatively impacted the indigenous cultures of the Caribbean. David Bennett's article, "Global tourism and Caribbean culture" offers examples in which tourism and globalization create an inauthentic culture that caters more to the tourists than the indigenous heritage.
