Do I have to have a credit card or can I use my bank debit card

If you use your debit card remember they will put a hold on it for the first night and 100.00 deposit ..

Yup can use your debit card. Doesn't have to be a credit card.

Plenty of ATM machines. You can definitely use your debit card.

You can use your debit. I just stayed there last week and used mine.
