Wordpress Plugin to Plan Tourist Routes

1 - Insert in BO (backoffice) POI (Points Of Interrest) with name, description, image(s), total price, reservation price, duration and geolocation for that POI (with lat and long); 1.1 - In BO should also be possible to insert preset routes (fixed/closed, not custom) ready for users to buy them. These will not be available for users to customize his travel; 1.2 - In BO must also be possible to set the cars of the company and the number of seats for each car (this will be used for system to calculate if # of persons, while reservation, is suitable for that car or not) there should be also a field for "extra cost" if that vehicle have an impact on price or not; 2 - In BO should also be possible to insert a price per km (kilometre) (explanation in point 4); 3 - In FO (frontoffice) users will be able to select POIs they want to visit and will drag and drop them or simply click on it and put it in a list that will automatically be done bellow (take these links as example: [login to view URL] - [login to view URL] - [login to view URL] ); 4 - Based on lat and long of those POIs selected by user, website will calculate route (not air distance, it should calculate route by car) showing total km and time, will show cost os each travel, adding previous POI cost to next POI cost so it show total travel cost (based on price per km inserted in BO [point 2] and on returned total km from Google) and will suggest user for best order of POIs to save travel time and money (e.g. if user selected POI A, POI B and POI C, website will check if it's better if travel route would be POI A, POI C and POI B and will show the improved suggestion in Google map with costs saved based on that); 5 - Users should be able to buy those custom travels or preset travels with preset routes (fixed/closed, not custom, like in this example: [login to view URL] ); 6 - Users insert total number of persons and system automatically sets a car (inserted in BO) and set the price change (if it applies); 7 - If users want to make a pre-reservation they should be able to pay a "reservation fee" (reservation price for travel/POI) which is mandatory, otherwise reservation will be pending confirmation from admin; 8 - Booking system should be simple: available dates depend on # of vehicles (e.g. #1 - If vehicle #1 [without extra cost] isn't available for days 1, 3 and 4 but vehicle #2 [with extra cost] is available days 1, 2, 3 and 4, a reservation for all those four days will be charged for day 1, 3 and 4 but NOT for day 2 because that day vehicle #1 [without extra cost] is availble; e.g. #2 - If all available vehicles are occupied days 1, 3 and 4 but one or more are available day 2, user should not be able to book for those four days but only for day 2) 9 - In BO we should be able to confirm reservations that are pending (only non-paid reservations will have confirmation pending, not closing those days in calendar); 10 - Automatic emails should be sent in these cases: 10.1 - User registration; 10.2 - Payment confirmation; 10.3 - Reservation confirmation (after payment); 10.4 - Reservation pending (if user chosed not to make payment); 10.5 - Reservation confirmed/blocked/still pending/need more info (depending on admin selected option for pending reservations)
