tuft regarding Tacloban Rob is the man who knows the area, his advice is invaluable ! Personally I don't use debit or credit cards when I am on tour, cash is King in phils, and that's good advice ! Travellers checks a white elephant, credit cards rarely get approved always seem to come up "transaction declined" ATM machines always offline and debit your balance without dispensing cash.
YOU HAVE BEEN WARNED !
