Not many people will appreciate what we have to say here, but we'll go ahead and say it anyway. That's just how we are: bold and brash. Your credit card limit will definitely make or break your vacation. There is absolutely nothing worse than running out of credit mid-vacation and having to come up with creative ways to pay for every little thing. Seriously, been there, done that, wasn't fun.
All this to say: you should definitely think about your credit card limit when you go traveling. And then, when you're done thinking about it, you should probably think again.
