It saves a lot of time waiting for buses, changing buses, and walking during the trip. You can chat and confirm attractions on the bus, and sleep whenever you want—it's so convenient!
Due to the itinerary, we went straight to Karuizawa on the first day and didn't realize that the Tokyo Wide Pass I bought on KKDay could only be redeemed for physical tickets at Narita, Tokyo, and Shinjuku stations. I am grateful to KKDay customer service for their assistance in canceling the ticket (after deducting a 10% handling fee).
I finally made it to World Square, a place I'd wanted to visit for a long time. Even as a couple in our sixties, there were benches everywhere and plenty of misting systems to help us cope with the heat, so we were able to enjoy looking around. The park isn't that big, but it brought back memories of when I was a child and was thrilled to see the Licca-chan dollhouse, so I was able to take my time and look around thoroughly.
I was glad the ticket exchange went smoothly. I recommend booking tickets in advance.
Unfortunately, it was raining, but it wasn't crowded so I was able to look around at my leisure.
