We just got back from Las Vegas over Easter and stayed at the Bellagio. We like the place and always enjoy their conservatory and gardens which is rotated often and usually theme based matching the season and time of year.
They had a spring time Japanese theme in place over Easter, which we thought was done nicely but somewhat unusual. There were lots of flowers, beautiful trees in bloom and Japanese umbrellas hanging upside down from the ceiling. The setup was done nicely; we just thought the timing was a little off.
