Next trips booked! Las Vegas (work); Paris (family)

I've got my next two trips booked!  The first is to Las Vegas for work.  ;)  I'm going for my industry's largest trade event later this year.  Something memorable always comes about...

I was also able to redeem Delta SkyMiles for four non-stop low-miles business class awards on Air France's A380 from JFK to Paris-CDG for February break week.  This will be the kids' first trip to Paris - I'm sure they will love it.  Still recuperating from the cost of Hualalai, this trip is going to be an entirely points-based trip.  Beyond the four business awards, I booked two rooms at Le Meriden Etoile using my remaining SPG points.  Certainly not the best hotel in Paris, but we were able to confirm upgraded rooms with our SPG points.  This will be my first trip where the flights and the hotels - for my family of four - are completed paid with points.

If you have any suggestions for family activities in Paris, I'd really welcome them.

Detailed trip reports to follow.
