Some merchants do, but be prepared with some cash. There are plenty of ATM around Winter Park.
Its per vender basis. Some do accept cards. Some do not.
Some vendors do. If you go to the building, there is a table there that you can use your credit card to buy "tokens" to use for those vendors that don't accept cards. The majority do. Or local personal checks.
You'll find a number of vendors do take credit cards, but I highly recommend bringing cash just in case.
