I always bring cash in addition to (2) credit cards designated just for the trip. I have a crappy story from this last trip in Feb....
We always use our discover card from NY to FL for gas and some purchases in WDW. Everytime we make the trip, it is flagged for possible fraud because it is used out of state and we end up having to have to get it re-activated through customer service with an explanation why it is being used out of state. We have even called ahead of time to give them the heads up, but it never helps. We always get shut off at some point by the time we get to FL. This has been going on for years now. So this past time some discover person had turned it into the investigation department for fraud and they couldnt turn it back on without issuing us new cards. We tried to explain this happens everytime to us, we even called ahead of time, just turn it back on. They kept saying they could get us new cards within 10 days, that they cant re-activate it because they opened an investigation. BUT THAT DOESNT HELP US WHILE WE ARE AWAY AND NEED IT! So that card was out of the picture...
So we decided to use our Visa (which we primarily use for food only). Our first night there we were at Le Cellier. Our bill was around $70. We gave the card to the waitress and she brings us back the receipt, except it was for $250! (someone else's bill, no thank you!). So she had charged our card the wrong amount. She said she would fix it, brought back the corrected receipt (not the in-between corrections showing the credit back onto the card. I didnt think about getting it. I just wanted to get out of the restaurant with my antsy 5 & 3 years olds). So a few days later I went to go buy ice cream and my cc was denied! So embarrassed
, but then ed! Wait, I know I had plenty of credit, the card was paid off before we left! So we called visa and Le cellier had made a mess of credits and charges and the card was all locked up with transactions trying to post from a few days earlier. Since it was a bank credit card (not a debit), I had to speak with the bank, who was closed until monday (this was a saturday night). We were leaving then.
So long story short, I was glad I brought plenty of cash. By the time we got home we had new discover cards and the visa was working again with plenty of credit available as expected.
