April, for spring is certainly a best season to get to know Holland. I'm sure you will amazed by the color and variety of all the flowers. You won't be able to stop taking photograph! We have many beautiful towns. I suggest you start by taking a boats trip on the Canals. It's a relaxed way of visiting the old canal houses. Then you can visit to our museums and churches. You don't have to worry about language problems there. Just have a pleased trip and come again next year.
