I'm traveling to Spain on Tuesday for about a month.
I originally planned to use my Discover credit card, since they told me it would be widely accepted internationally, but I've recently heard otherwise from people who've traveled there. My only other card is my visa debit card, but that's linked to my main income and I'm not comfortable relying on it as my only option while abroad. I'm trying to figure out what credit card I can get quickly (ideally before I leave in 4 business days) that would work well in Spain as a backup for purchases and emergencies. Any recommendations for fast approval cards or travel-friendly Visa/Mastercards would really help. I was thinking of getting the Costco Mastercard but it'll take a week or two to get through mail.
