ATMs dispensing pesos are widely available. Credit cards are accepted at hotels, restaurants and some shops in all but remote areas.
Restaurants 10% service charge added to bill in cities and tourist hotspots. Otherwise leave 5% to 10%.
Taxis Round up taxi fares, but consider tipping more (P50 to P70) for honest taxi drivers who turn on the meter.
Hotels Not expected, but slide P50 to porters or leave a few hundred pesos in the staff tip box at resorts.
Guides Always tip your guides, as they can really use it.
