Qns : Can we see the fireworks for Disneyland from Disneysea

7 July - (Asakusa ,Shinjuku shopping etc - back to Singapore)

I have no idea what I should do on this day. Any suggestions?

I recommend to decide based on your personal interests. Also, since I believe that the one day trip to Furano is too busy, how about using the day to extend your trip to Furano by one day?

Can we see the fireworks for Disneyland from Disneysea

I will follow your suggestion to stay another day at Furano. However, can I check if I should stay at Asahikawa or Furano.

My worries for Furano is that I might be too early for the lavender season if I am there for 2 days there might be nothing for me

Is Asahikawa worthing visiting or I should go try the dolphin watching

I think chances are pretty high that the lavender will eb in bloom by early July. Furthermore, there are lots of flowers besides lavender, which are nice to look at.

Thanks, I think I go over and stay 1 night at the pension over at Furano.

Can I check if I am allow to get and play any fireworks in Hokkaido since it is not allow in Singapore.

Last but not least, with my Hokkaido plan, do you think I should get the Hokkaido rail pass. My plan is Sapporo, Otaru,Furano and back to Sapporo

What are the opening hours like?
