Does anyone know or have experience with Ice Skating at the eiffel tower? I will be in Paris from Dec 25-31, and a friend of mine at work, that had lived in Paris at one point mentioned it to me...

Also, one more question although im sure the answer is yes, the Metro and RER will be up and running on the 25th correct? I land at CDG that morning and plan to take the RER in to town.

Thanks,
