Hi Pare, Kamusta na???
I was born in the Philippines but grew up in Australia. Indonesia vs Philippines? can't really compare much. Everything are exactly the same in regards to weather and traffic. Cost of living, its a bit cheaper in the Philippines. The only differences are the culture, religion (95% Catholic 4% Muslims and 1% mixed religions) which here in Indo its vice versa, 95% Muslims etc...
Your wrote that you're concerned about cost of hotels, restaurants, taxi fare as it seems to be a bit more costly? Also on cultural differences.
Cost of hotels are the same. Maybe its only few dollar differences. I'm sure that you can find cheap hotels here as well, but its cheaper to rent an apartment if your staying long term.
Restaurants are not that expensive, its the same cost if you have dinner in Greenbelt, Makati. (not sure if thats where you hang out, but most tourist do hang out there). Taxis are also same price compare to the Philippines.
I'm married to a beautiful Indo, that is why I'm currently here.
