One of the best experience gifts is a night at the circus, and in particular, the renown Cirque du Soleil. Tickets range upwards from $64.
Savvy pick: You can find plenty of free or reasonably priced events going on in your city if you do your research. Duck tours are always a boatload of fun, and they are priced around $30. Another favorite event of mine is night-time viewing at a museum here in San Francisco ($12).
