If you've taken this cruise, please provide any suggestions. For example, shat is best "week" to go to see maximum flowers? Any other suggestions for this cruise? (I have cruised Viking previously, but not this cruise).
I'd recommend the last two weeks in April, when the tulips are at their peak. I believe that the phenomenal Keukenhof Gardens (with 70,000 different types of bulbs in bloom) closes about May 10th. Be sure to visit Keukenhof on your own if Viking does not include an excursion in conjunction with the cruise!
