This is a great free family friendly activity for both locals and visitors on the strip. The Conservatory and Gardens are located inside of the Bellagio Hotel & Casino and are therefore air conditioned so it is also a wonderful option during the hot summer months. They change the displays completely with each season. My teenager loves it in all seasons. I have found that my little kids (2-5) prefer it during the day. I took them last fall when it was decorated with a Harvest theme and it was at night and a little darker with lots of people. They were a little overwhelmed. Today (July) we visited during the day and it is a Summer theme with a lighthouse, kites and birds and they loved it! They also really liked the glass display on the ceiling of the lobby and the flower display behind the hotel registration desk which coordinates with the Conservatory theme. The summer display includes live birds in the center glass "green house". This is a great stop if you are taking in the fountains outside. Note that the fountains don't run during the weekdays (only at night). There is live music in the evening, pretty sure the sign said from 5:30 - 6:30pm and this morning about 11 am there was a staff member out as Mr. Green Thumb answering questions about the gardens. Exploring the gardens takes just about as long as a toddler or preschoolers attention span lasts so its great for that age range. Older kids and adults can look at more of the intricacies of the beautiful displays.
