Stella, you will love Paris! It is really nice, we stayed there for our first time in Nov. and we are already going back in 20 days. When we went in Nov., we asked for a fountain view(we had a normal standard room) at the check-in at the airport. The woman we spoke to said it was $40 extra per night. We chose not to go with view so we had extra money to spend, but this time we are definitely paying the extra money. Our room was clean and nice, and I really couldn't find anything about the hotel to complain about.
If you have some extra money to spend, ask for a LeMans suite. It is totally and completely amazing. Stayed there last year for our honeymoon, and we loved it. These rooms are mostly on higher floors.
Ask for a room at the end of the hall way. That would be the corner rooms. A little larger but better views.
Since this is your first time in Vegas, I would DEFINITELY ask for an upgrade to a Strip View room for $40 per night extra. The view of the Belaggio Fountains is amazing! If it was not your first trip, I would just recommend the regular "deluxe" room. All of their rooms have a separate tub and a glass enclosed shower. Their buffet is one of the best on the strip. Have a great time!
