It's a NO-NO to go late to a resort during summer weekends in Subic, as walk-in guests, particularly on a Saturday. It seems everyone is heading to the beach during that time. Everyone wanted to beat the intense heat!
Inside Subic, there are only four beach resorts - Camayan, Adventure, Sands of Triboa and All Hands. For day tours, advanced reservations for the cottages are not allowed. They all observe the "first come first serve policy".
