We've stayed at the Bellagio a few times and it is definitely one of the most spectacular resorts on the strip.  We had the premier fountain view room and watching the fountain show is one of the reasons I chose to stay here.  I also love the beautiful conservatory, gallery of fine art and all the shops and restaurants.  My all time favorite Cirque du Soleil show \"O\" is at the Bellagio.  The only downside is that it is very crowded especially during the holidays.
