The Bellagio Conservatory and Botanical Gardens were the only things going for the Bellagio in my opinion, besides the watershow of course. We got here late at night, figuring that it would be relatively quiet despite being open 24 hours. But to our amazement, it was jam packed with tourists.
The Conservatory is a definite change of pace from the ramble and gamble of slot machines, and high limit poker. If you need to take a breather and relax among a forest of flowers, the Conservatory is the place to go too. More colors then I can count, miniature round waterfall fountains, Bees and flowers hanging from the ceiling, and The Garden Frog which watches over the garden designed out of moss, there is a ton of "Life" to experience here in the Conservatory.
Cheers
