Seconded about Tour Montparnasse. The Tour Eiffel has become an expensive, crowded, dangerous nightmare. You have to go through airport-level security just to approach it, and going up requires previous reservations or waiting in very long lines. Tour Montparnasse is as pleasant as Tour Eiffel was 20 years ago. Tip: Go just before sunset and stay at the top as the sun goes down. Paris is loveliest during the sunset transition.
