Start with the available days
Count usable days after arrival and before departure. A transfer between bases also consumes time and adds another weather-dependent connection. For a short stay, concentrate on one area and choose activities that start nearby.
Ask about the actual island route
A tour name can cover different sites and inclusions. Check the departure point, current permits, meal arrangements and whether equipment is included. Make sure the day suits everyone’s swimming confidence and mobility.
Private or shared outing?
A shared trip may suit a solo traveller or a couple who value lower individual cost. A private boat may let a group agree a pace, but it does not remove access rules or guarantee empty locations. Compare the complete cost and the approved route.
Plan around weather, not just months
PAGASA describes a broad December–May dry season, but the Philippines has several climate types. Check local conditions and advisories for your dates and keep onward travel flexible enough for a changed sailing.
Build in a slower day
A day without a boat departure provides a buffer and a chance to explore your base. It also makes a sequence of early starts more comfortable. Use it for rest rather than filling every gap with another excursion.
