Yes..there were extra costs. but the overall costs were greatly reduced (by using Marriott Points) by not having to pay for the hotel stay. I have learned from Pingreeman that Marriott points get you a lot more bang for the buck than other hotel chains!!!
Recently used points in Paris, and a comparable Hilton property was three times the amount of points as the Renaissance. Don't forget the CL's, I figure that is equal to at least $100 per day for two people.
