Fantastic. This is a great way to use a watermelon that's good but not great and/or just too large to get through. Made it without ice, using a food processor (I don't have a blender), which worked fine. As other reviewers noted, seeds are not a problem as they don't get chopped up and are just sieved out. Then had a brainstorm: made 'Wellinis' - variation on Bellinis by adding the watermelonade to half glasses of prosecco. Gorgeous and addictive. A sprig of mint made it super festive. Our neighbors raved, and being Italian they are hard to impress. Any dry sparkling wine would work well for this kind of appertif and for my 3 year old, I added it to half a cup of sparkling water to make 'bubbly juice', as she calls it.
