Theme is tropical bright colors. Semi-formal beach attire. We suggest you wear linen (can be beige but not white), khaki, button down short or long, sundresses or any dress with bright tropical colors! :) Just make sure its breathable and lightweight if you are not used to hot and humid weather.
YES! LOTS OF TOURISTS ALL OVER THE WORLD VISITS SIARGAO OR EVEN STAYS AND SETTLES THERE. YOU WILL BE SAFE :)
Mostly taxi or GrabPH ( just like uber) - You have to pay cash though! So bring cash!
Manila is safe in most places but I would stay vigilant! Theres a lot of pickpockets! Specially if you are a foreigner. Unfortunately. Just stay with the group, be vigilant and you will be fine!
You can only bring $10,000.00 worth of cash going to the PH. But you will mostly need cash - Again, lots of pickpockets (in Manila) so bring enough with ya only when going out.
