Hello,
This is something I've been wondering about, and it influences how I'll manage my next trip to japan and amount / length of the passes.
Last time, with a 7day pass, I've had my 6th seat reservation "stamp" put into the relatively small field on the back of the pass. There was no additional space left, but I also had to go back, so it was unneded. I also was mostly using the lines that I didn't require a reservation, so I was safe. I've never checked what happens if I try to get a 7th, etc reservation on that JR Pass. And that's my question.
I was wondering, how that exactly works.
For example, my upcoming trip is 24 days long. I'm considering either 21 or 14+7 passes for that. I'm also planning to use it a lot, i.e. for the initial 4 days, I'll most certainly have to use around 5 seat reservations in order to get where I want. And if I'm keeping the pace, if the space wasn't just 6 tiles for stamps (with 1 mandatory stamp for the initial ride), I'll need around 20-25+ stamp spaces in total, at least. :)
What's the ground rule for that? Will smaller stations be having issues with a JR pass that's literally riddled with stamps after some time of heavy use? Will it create issues for my schedule, if I'm constantly questioned or encounter puzzled station attendants? :)
Thank you very much for any answers and best regards!
