My husband and I stayed at Paris for three nights (Fri-Mon) last week. Our room was beautiful and clean, with a view of the pool. Paris' pool is lovely--not huge, but gets great sun, has a DJ and a food/drink bar. The location really can't be beat. It's dead center of the strip, across from the Bellagio, with a CVS right up the street for all your alcohol and hangover needs. Vegas, in general is expensive, and Paris is no different. We ate in the hotel restaurants once, breakfast for 2 was $50. Staff were very nice and accommodating, and when there was a mix up with the price of our third night, the front desk was helpful in clearing it up. Also, there is a $40/day resort fee, which can bring up your price, even if the room price is low. You can't avoid this fee in Vegas though--every hotel charges it. Parking was easy and $10/day for self-park.
Overall, I would recommend Paris when you stay in Vegas.
