my advice do your own research and don't depend on others,
there are a lot of youtube videos out there, that cover all travel experiences,
here is a list of things to help you out,
luggage -what to pack
passport and visas requirements
travel insurance
covid vaccinations and PCR testing
airport procedures and delays
hotel bookings-cross reference with Tripadvisor, hotels combined and the hotels own website
transfers-see if the hotel offers free airport transfers with bookings, otherwise uber or a chauffeur never trust taxis on long trips
money exchange
scams and crime
nightlife

as for the Philippines just google best holiday designates in the Phillipines
