Welcome! We did just what you're doing this spring for Iceland/Ireland/Scotland on the Reflection.
Price was so good we just HAD to do it! We had a great time too. Everyone on CC was helpful in getting my planning of tours done & we had just 1 month before our sail to do it all...Being that we are in Kobe port overnight, I'd recommend you do day tour. For example: We are doing a Kyoto day trip using the fast train and a half day in Osaka.
Or you might opt for Nara daytime and Osaka in the evening the first day and then see Kobe or Mt Rokko area before we sail out of port. I have my bookings with Triple lights private tours for just 2 of us. About 100 p p not including meals, and we meet our guide once off train from Kobe to Kyoto & Osaka.
I should explain we are doing a Bk2Bk from Oct12th, so we will already have a bit of experience in Kobe port from Oct 14th. (9am to 12:00am) port time. We have a different guide for that stop, also booked through Triple lights. Will meet us right at the port to take us to Nara for day and then Osaka for sunset. We'll have dinner there and travel back to port from that train station on our own. If for any reason we aren't into that, our guide will take us to the Osaka station and see us off for a safe departure.
If there is any info I can share, such as transfers, or just general info-I've been good friends with map quest and trip advisor for this whole experience LOL!!! Don't hesitate to contact me firstname.lastname@example.org
