Here's what I'm trying to achieve.
Package is a product which includes a certain number of night stay in each city. I want the user to be able to select which hotel he wishes to stay in (different hotel, different prices)
I want to calculate the price of each product based on the price of the selected hotel.
Total Price = Package Selected Price + City1 Hotel * No of nights in City1 + City2 Hotel * No of nights in City2
Please help on how this is achievable.
