Hi :)
I want to go island hopping in Greece with your Greek islands pass for about a month, and I can buy either four travel days in a month or six travel days in a month, but I want more than six travel days. My plan is to buy two passes with four travel days and then have eight travel days in total, but I want them over the course of about a month and not two months. So for example:

I start my trip and activate my first pass on the 1st of September. Then I travel on the 5th, the 9th and the 14th in the same month. Then I activate my second pass (the first will still be active until the 1st in the next month) and I travel on the 17th, the 21st, the 27th of September and the 2nd of October.

Do you know if its possible?
