What Does the Inside of the Louvre Look Like?

I’ve had the honor of spending, oh, about 10 hours in Paris. During a lengthy layover, I rode the train into town, stood outside Notre Dame, ate lunch at an outdoor cafe, hopped a bus to the Eiffel Tower, trudged to the Louvre, returned to the train station, and then headed back to the airport. It was an exhausting day — man, I sure coulda used one of those free bikes! — but it was fun.

Unfortunately, although I got to see a lot of stuff from the outside, I didn’t get to see much from the inside. I never entered Notre Dame. I didn’t ride to the top of the Eiffel Tower. I only marveled at the architecture of the Louvre’s front door. Frankly, I was afraid to invest too heavily in any single activity for fear I’d miss out on something more fun — or miss my flight. On one hand, I’m glad I got to see so much of Paris, whirlwind though it was. On the other hand, if I could do it over, I might’ve chosen one activity, spent the whole day doing it right, and forsaken the others. Dunno. Nevertheless, I stumbled on this 9-minute clip shot (no doubt clandestinely) inside the Louvre. Now I see what I missed.

Did I make a mistake tackling Paris this way? Or was I wise to do what I did, given my time constraints?
