My partner and I found our entire experience with the Kröller-Müller Museum superb. There's one small group tour that is recommended by the museum on their website. We set up a day tour from Amsterdam to the museum using that link. There were 8 passengers in a large Mercedes van with a talkative driver who took us directly to the museum via the shortest route possible.
We took a short walk to the ferry which took us to the meeting place. The total time involved in traveling and visiting the museum was from 8:30 AM to about 5:45 PM. It was a very fine day trip. I think it was the least stressful way to visit the museum but of course it would cost a bit more than trains and buses.
I'm an art historian/artist and my partner is an interior designer. We loved the second largest collection of Van Gogh work housed at the museum as we could actually interact more with the works without the throngs always found at the Van Gogh Museum. There's one key piece that most art students will instantly recognize but many others worthy of your time. There's a surprising number of works by Vincent's contemporaries that will engage you. I fell in love with a Cezanne painting that I had not seen before.
The sculpture garden has more modern works than the museum. It's rather large and a pleasant outdoors break. There's a cafe sufficient for a coffee/tea break or lunch indoors and outdoors at times as well.
I'd enjoy a return visit any time. I wouldn't pay much attention to the youtube videos especially if you are seeking post-impressionist work.
