Good vibes, great itinerary, comfortable vehicle, supportive and friendly tour guide from PST Travel, Jeremy who is a trilingual speaking both English, mandarin and Japanese- he was funny and informative, I appreciate that there were moments of silence for us to rest during the journey too as all of us are tired from waking up earlier and long car rides. He brings us to instaworthy spots and helped to take pictures, he also kindly provided us with food recommendations and any other info u need for traveling in Japan. As a solo traveler, I feel safe and well taken care of. Gold class tour guide, he deserves an accolade for his above & beyond services. Kudos
When visiting the Otaru Aquarium, you absolutely must see the penguins walk. Buying your tickets in advance means you don't need to queue; just scan your QR code for entry – it's very convenient!
Very fortunate the weather was clear when we arrive. The free postcards are at cashier and not those on sale. The station allowed redemption of the tickets even when I arrived one day before. There is also a ski museum.
