I´m sorry Geri, but I´m not familiar with your debit cards.
We have special ATM machines, located outside of different banks and you can use them, to get money with your creditcard, like Mastercard, Visa.
But I guess, a debit card is different.
You will probably see some christmas decorations, but unfortunately the christmas markets close on december 24th and thats what Germany is famous for.
But I´m sure, that you will enjoy my country, so as I enjoy yours. I have been in New England with a cruise and have been in Florida several times and I love it.
Best wishes to Florida
