Barcelona but no Andorra

We have booked a short (and cheap) holiday in Barcelona which we will take before the end of the year. £350 between the two of us, flying BA, 5 nights, is a bargain. Thank you eBookers. We will spend some time shortly checking out places to visit. I have visited over 50 countries but Andorra is not on that list. My aim is to visit as many countries as possible but sadly, it looks like on this holiday, we won't be able to get as far as Andorra. There are no direct train services from Barcelona and it takes 3.5 hours to get there by bus. We would only want to visit Andorra on a day trip from Barcelona but we would end up spending more time travelling than visiting the country. That doesn't seem worth it. So we will spend the whole of the holiday in Barcelona instead.
