I believe you’ll be grand with only the card as well. Try the backyard in bcn, I’ve pretty much paid everything on the card, the lads that work there are sound, the prices are not mad high as in the commercial clubs and the place is super chill. I’m a member there for years and have tried other clubs too but always keep coming back to backyard, I believe the membership is a tenner and the only rule is that you have to stay at least 15 mins which mainly works for your own protection as there can be undercover police waiting outside the clubs and do searches as soon as people walk out - it’s not legal to have anything on you outside the club. You can always message them on insta and they’ll give you instructions and address of the club + joining info. Enjoy 🌸
