I don't know what your dates are for your search, but I was also looking at a Hotwire 5* Georgetown hotel deal and I think it is the Ritz-Carlton, Georgetown - my dates are 06-08 July 2015. It is the only 5* I can find on Hotwire in the Georgetown area. However, this hotel does not appear to have a pool, like you mention in your first post. I searched a bunch of different dates though and the only 5* popping up ever for Georgetown lacks a pool. I'm fairly certain it is the Ritz-Carlton, Georgetown.
