I saw La Reve about 4 years ago and really liked it. I have not seen "O" yet. My wife (who hasn't seen either), really wants to go to one of these two shows during our upcoming trip. The tickets for O are much more expensive than the tickets for La Reve. Has anyone seen both that can comment on which is better? I would like to see O since I haven't seen it, but I don't want to pay $150 more to see O if it's not much better than La Reve. Thoughts?
