In order to attract tourism, provide an estimate of the cost of a weekend trip for each city in the UK. This should be done by first creating a list of all UK cities, finding the average price of a hotel stay for Friday and Saturday night in each city, determining the average star rating of hotels in that city, determining the number of restaurants in each city and the average price, determining the average cost in each city for a pint of beer, determining the number of free attractions and their average rating, and finally crating a ranking system factoring in all this info, with hotel cost being the most important, to rank the cities in order from most to least expensive.
