I haven't stayed at the Venitian, but the Bellagio rooms, standard suite $350 - incredible room, Master suite on the top floors $750- haven't been in one, but, if they are any better then the standard suite it has to be amazing.
The rooms screem of opulance. You enter into a living room with a bathroom, couches, TV, table & chairs. Pust a button and the curtain opens up. Go into the bedroom and find decadence at it's best. His & Hers bathrooms with a TV in each. Her's has a tub, his has a shower (Marble) that becomes a steam sauna with the pull of a lever. The shower is sealed so well that if you close the door you can't hear the water running.
It's an amazing experience.
If moneys not a problem, almost any of the major resorts have incredible rooms. I particulary like the Paris for affordability, location and a great buffet (breakfast). However, in light of recent events, I don't do French anymore.
Now that I live here, I don't get to stay in the Hotels anymore -but- it's a great place to live. Bring on the Summer Heat!
