As beautiful as Bellagio and their things are, the spa was pretty compact without anything remarkable. Pretty disappointing after coming in after seeing their thematic gardens just below the balcony. The gym was nothing remarkable either, just packed full of the regular equipment and overlooking a pool area you couldn't go into.
A day pass for non-hotel guests is $40. For that price, Canyon Ranch at the Venetian offers a whole lot more in space, lights, features, and extras.
