Philippine Peso - Travel Money Saving Tips
There is a lot more the Philippines than just Manilla so try to get out of the capital, do a little research beforehand about the few possible bad areas and you will be fine. There are ATMs available in most decent sized cities but more than a few travelers have been caught without access to ATMs when getting out of the majors cities, and a lot of popular destinations are nature spots so carrying some cash on you is a good idea. Also using a Prepaid Travel Card can be a good idea so you don't have to take your credit card everywhere on you. Only drink from bottles water and make sure it is properly sealed when you buy it.
For getting around buses are the most commonly used means of transportation. Second to that are ferries. On arrival at the international airport the easiest, and most expensive, way to get a taxi is take the White prepaid Taxi. First line on the right of exit. A trip to Makati or Ermita will cost you 500-600 pesos. Normal cheaper taxis are available upstairs on the 4th floor, these should be white coloured also.
For local trains in Manilla the three line LRT/ MRT elevated railways are a travel bargain and very cheap. While they don't go everywhere, an indirect trip via Taft and EDSA stations (connection is via an overhead footbridge then through Metropoint Mall) is a good way to avoid a taxi clogged in slow traffic.
