So me and my friends are traveling to prague next week and we are all full time study in sweden. I see that multiple places have student discounts if youre able to show a student id. I have a student card that we were given by the school but that just shows a picture of me and my name and when i graduate. We also have a bigger student card like isic but for sweden that is called MECENAT.

I wonder if i will be able to still get the student discounts if i show my school id or MECENAT card or if its better to pay the 18 euro to get an ISIC?
