The Floriade was somehwat dissapointing after the Kukenhof Gardens. The Floriade stressed agiculture rather than flowers which is what the name implies. Viator's tour was fine giving enough time to see everything at the Floriade if you could walk that much. The tour guide was very informative on both the trip up and back.
Fantastic gardens even though we went on the last day it was open. It's probably best to see this in late April when the tulip gardens are in full bloom, but what was there was definitely a "WOW." We took the 12:15 3/4 day tour which gave sufficient time to see everything (although a full day in April would be better). Viator basically provided the bus trip back and forth with admission to the park.
