I like to stay at Paris - it really is convenient to everything on The Strip.  Since you are in the Harrah's family, there are lots of places to use your club card to rack up comps.  I like the layout of the casino and the setup for the video roulette - how lazy can I be???  We cab it to Mandalay Bay for concerts - it is quick and easy.  Our new favorite bistro?  Mon Ami Gabi - i think the Parisian theme is fun since I am unlikely to ever visit the real thing.
