I've seen agoda and asiaroom websites excluding taxes from the prices of hotel they show you, then add it in in the final payment pay.
However, the price i see on booking.com eg $100, is the final price I see on the final payment page. I'm a bit skeptical, is booking.com hiding this tax and requiring me to pay this extra tax to the hotel itself? For this particular hotel, booking.com requires me to pay the hotel upfront..
Btw the hotel I want to book is actually alta vista boracay loft suite apartment @ 4000php a night, not the alta vista de boracay (which charges almost twice the price)
