Almost no lavander at the Furano Farm in mid-June and a couple of shops were not opened. But the other three attractions (though also not many flowers at 四季彩之丘, there were two patches of flowers including lavanders) were very nice and everything about the tour was smoothly executed. The tour guide 小蔡 did a nice job. Introductions to the attractions are detailed and he can speak Mandarin, Cantonese, English and of course Japanese. The company contacted me on WhatsApp the next day after booking, and instructions on the meet-up point and return time to the coach at each attractions are clear. At the end of the tour, the tour guide recommended some restaurants in Sapporo, which is a bonus.
Highly recommended if you don't drive.
