I transit through Paris on my way to Conakry, Guinea later this week. I arrive via IADS and MUC on the 13th and leave the next day, late morning. Y all the way

Is it worth heading downtown? Any hotel suggestions near airport shuttles?

I'm thinking of staying at the airport in order to watch the planes take off and land. Any particularly good hotels for this?

Thoughts/suggestions appreciated!!!

P.S. I posted this in the Paris forum, but traffic seems pretty dry over there. Please slap my #ss and call me Sally if this is the wrong forum.
