I bought a senior ticket for my sister, not realizing it is for EU citizens (which we are not). It does not specify this in the area where you select tickets. But it does say it elsewhere on the website (which I discovered later).
Has anyone else done this and been allowed in? I did have to enter passport info when making the purchase, including the country. Is this necessary when purchasing the regular tickets? I’m happy to buy another regular ticket if we are likely to be denied entry.
