Summer is the best time to spend a vacation most especially if you are with your family. Booking for airfare ahead of time is the best way to save some penny. Since  the airfare will increase during peak season such as summertime.  In Puerto Princesa, we stayed in Prima Residences . They also offer the package tour cost Php 3, 950.00 which includes half day city tour, famous Underground River, Honday Bay.
