北海道自由行5日4夜(札幌>小樽>富良野/美瑛>旭川>函館>札幌)

Since you have only 3 full days for sightseeing, I do not recommend to go to函館 since it takes 3.5 hours from 札幌. You do not have enough time to come back to 札幌.

In winter, there are no flowers in富良野 /

Suggestion for Winter (Oct- Mar)
Day 1 ->札幌, Dinner at 札幌
Day 2札幌 ->小樽 (住小樽住宏樂園浸溫泉)
Day 3小樽->旭川
Day 4 札幌 ->函館 [Better stay at函館 hotel]
Day 5 Leave from 函館 Airport (ANA flight / JAL flight can leave from 函館 instead of 札幌)

If you cannot leave from 函館, you better stay in 札幌

Note : 札幌 ->函館 needs 3 hours, therefore cannot have enough time to get back to札幌.

Suggestion for Summer (May - Sep)
Day 1 ->札幌, Dinner at 札幌
Day 2札幌 ->小樽(住小樽住宏樂園浸溫泉)
Day 3小樽 ->旭川
Day 4 札幌 ->富良野 / 美瑛
Day 5 From 札幌

小樽 - 小樽運河, 壽司屋, 北一硝子（玻璃）3號館, 小樽八音鐘堂
