I don't think I can find a single bad thing to say! We got a great deal, something like $80 a night in July. Did the $20 trick and was enjoying a strip-view room at 1PM on Saturday.
Restaurants were great (Japonais: pricey but tasty. New burger joint: AWESOME!). The pool was perfect, although in July it was just too damn hot for us to stay outside.
Spent enough time in the casino to get the $10 dealers to know me by name. Even won enough money to pay for tattoo at Vince Neil Ink (see separate review).
Location is perfect. Right across from Venetian, TI, even a Mickey D's and Chipotle is right there. Take a walk down to O'Sheas for some cheap craps and Beirut ("beer pong").
We even did the corny Tiger and Dolphin tour. Only regret is not checking out Bare on Monday, but like I said it was too damn hot.
The Mirage is friggin' awesome. Makes you feel almost like a rockstar without emptying your bank account. We're headed back this spring for sho.
