Moonlit carriage tour of the monuments I would take out. Better off doing it by car.

Citronelle is better than 1789, but is priced as such and then some. (It wasn't always that way.) A walk from 1789 to the FS hotel is more of "downhill" and a real walk than a walk from Citronelle to the FS, which is far shorter. (And if it's a weekend evening, the streets in Georgetown can be a bit busy and then some.)

The Four Seasons in Georgetown is good and I like it better than the RC Georgetown. But, at the FS, get one of the better, updated rooms there with an actual half-decent view/light. At the FS, the Garden Terrace for afternoon tea is good if the weather is not so good.
