I suppose this is as good a place as any to ask a completely unrelated to a cruise stupid question, so here goes, has any ione rented a car using a Visa debit card from your bank account? (flying to Tampa in 2 weeks to visit family) I don't own any credit cards, I know that I rented a car with Dollar in January using my debit card, but I seem to remember having to pre certify or something? HELP!
