Q: If I purchased a 4 day Barcelona Card then used it 2 days then 1 week later used the other 2 days, is that OK?

A: Unfortunately the Barcelona Card does not work like that. You purchase the card for the number of consecutive days you intend to use it for. For example if you buy a 4 day Barcelona card on a Monday it will be valid until the end of Thursday of the same week.
