1. What is the best (cheap & efficient) way to get to and from the airport to the Le Grand Paris hotel? you mentioned the Air France bus. Can I take that bus if I am not travelling on Air France?
Yes, it departs from both terminals and can be used by anyone, not just AF passengers. Not sure what the fare is these days, but likely E10 or so. I am sure there must be a CDG website with this information. It is called the ROISSYBUS. It is express into the city and terminates across from the old Opera, and a half block north of The Grand.
2. How far is Le Grand Paris from the Intercontinental Paris?
About a 10-minute walk up rue de Paix and it is just before you get to the Opera. You leave the IC by the side door and walk up rue Castiglione and through the Place la Vendome and you'll hit rue de Paix. Keep walking northwest along this street and you'll come to le Cafe de la Paix, which is part of The Grand.
3. Would it be feasible or worth the while to stay one night at each?
Yes, very typical FT behavior. That way you'll max your PC points too, since one only gets 2000 per stay, not 10 per US$ spent [plus elite bonuses].
Enjoy.
