I have booked a house at center parcs Heijderbos. I explicitly asked if there is a decent wifi connection to be able to play online. They promised to deliver this but now it appears that the connection is only 8mbit while you need 25mbit to play online. Even the 4g network of my phone is 4 times faster than this.
