The white stone steps of the famous Basilique du Sacré-Coeur, at the top of Montmartre, have the best view of Paris that doesn't require either an admission fee or a lengthy wait.
If you time your walk back down through Montmartre right, you'll be able to catch the Eiffel Tower when it's lit up for 10 minutes at the start of the hour.

Ice-skating in Central Park's Wollman Rink is a great way to get your sweetheart's pulse racing before popping the question.
When the weather's warm, the lake in Central Park fills with rowboats rented from the Loeb Boathouse nearby. Farther north, the Conservatory Garden's six acres are an equally romantic spot.
A bronze replica of Michelangelo's David anchors the Piazzale Michelangelo. You can get here via public bus, but a half-hour stroll through the Oltrarno district is a lot more romantic.
Piazzale Michelangelo's beauty attracts lots of tourists, so for the best effect make sure that your beloved is looking out at Florence below, rather than at your potential audience. (The bridge shown in front here, the Ponte Vecchio, dates back to medieval times.)

The annual Burning Man festival draws nearly 50,000 people to Black Rock Desert in Nevada for partying and making art. A marriage proposal here guarantees a large number of witnesses—and some highly memorable photos.
You may want to propose closer to the start of Burning Man rather than near its final, eighth day—showering here can be difficult.
The Kentucky Derby, "the most exciting two minutes in sports," has all the pageantry you'd need for a memorable proposal.
It's best to spring for grandstand tickets if you intend to propose at the Kentucky Derby; here you can sip mint juleps out of commemorative glasses while checking out the large, expensive, and frequently bizarre hats.
For relationships that are filled with iPods, computers, and other technology, the Macworld trade show, held in San Francisco, makes for a fun, completely geeky place to propose at. If the conference itself doesn't seem romantic enough, you can always escape to Crissy Field and its view of the Golden Gate Bridge.
