You're very welcome.
I hope you enjoy your stay in Florida.
I think it's easier to do everything with credit card, it's (a) much simpler, accepted everywhere, and it gives you protections you don't have with a debit card - they will dispute charges you don't agree with, etc.
You will probably find that as you use your debit card here for purchases a lot of small stores will not run it as debit with you using your PIN, they will bill as credit and you'll have to sign a charge as if you were using a credit card. It will still come out of your bank acct the usual way, but it gives the vendor some assurances they don't get from debit systems...
