I allways take some cash and travelers checks, if you lose or worse yet get ripped off of your cash you are SOL, if the same happens with travelers checks and you do as the bank tells you to do, keep your receipts separate from your checks, you should have some cash back to you in awhile after filing a claim. Also once you are there find out who gives the best exchange rate. They claim the exchange rate is two Belize for one US. But I have found in past travels of other areas the exchange rate is different from place to place.
Thanks for the e mail, one is coming your way soon.
