Lemme start. I have been to almost everywhere in our beloved country. So far I have only been to 3 places abroad, Qatar, Bahrain and Abu Dhabi.
Palawan is one of the best if not the best place to go to for relaxation. Boracay masyado ng commercialized tsaka sa dami ng tao during summer, baka lumubog sa bigat dahil overloaded na :D. Next target ko Bohol.
In terms of airlines, I take PAL Mabuhay class especially when going to Davao. Cebu pacific naman kung tight sa oras.
