The City of Trees offers an Awesome Pass, which offers discounted access to many attractions. In the basic package, you need to pick one of two bus tours, one of four museums, and one of two palaces. However, if you opt for the Historic bus tour, you have to skip palaces but will visit two museums instead of one. Also, if you choose the Museum of Brilliance, the only palace you could visit is the Palace of Magnificence (if you haven't chosen the Historic bus tour). Assuming the order of attractions doesn't matter, in how many ways can you spend your weekend in the City of Trees?
