Thanks for the inputs.
Still at early stage of exploring a possible trip there. Basically, wanted to know first whether without driving can still do a good f&e trip. I had been on a group tour before, covering Matsumae, Hakodate, Lake Toya, Otaru, Sapporo. Hence, I am more keen to cover eastern side this time like Asahikawa, Kitami, Abashiri, Kushiro, Obihiro, etc. Just names I see on the map, but not sure if there are anything worth visiting there.
Or I can just base in Sapporo and take day or overnight trips to Asahikawa, Biei, Furano, Otaru and Noboribetsu which I have not visited before except Otaru.
Problem is I can only go 2nd half of may which means missing cherry blossoms and yet too early for lavender at Furano.
