I know, I can't imagine going anywhere and paying cash.
I think like you - I just hate cash. But I understand many people have a hard time with the infinite amount they can maybe spend on their credit card. It just personally annoys the hell out of me to keep track where it all went.
Likewise, we spent little cash on vacation but I found our money vaporized anyways. Usually I look at Quicken every day or so. Which I don't have that luxury on vacation - nor do I want to track every dime, on vacation. But I have to write it all down and try to keep it under control orelse it does start to vaporize.
Sounds like it was fun!
