Hi!
Me and my friends (6 kami lahat) went there January 21-24 (both morning flights). Manila-Cebu-Bohol-Cebu-Manila Route. I guess hindi pa maxadong peak season at that time. Yung total gastos ko, personally, is a little over 7k for everything:
P1000 - airfare RT
P400 terminal fee Manila and Cebu
P750 - skywalk and edge coaster package (may free t-shirt!) tapos
P250 yata hati-hati sa CD ng pics
P800 roundtrip ferry via Weesam (cheapest din kasi)
P2599 countryside package tour (3D/2N alona groove with simple breakfast, countryside tour, lunch buffet river cruise, island hopping)
P350 or P400 - zipline (extra na kasi yun. pero ayos!)
P50 hati-hati ulit sa Photo CD
Tas mga taxi-taxi, extrang food esp sa Cebu, tip kay kuya Tour Guide, at sandamakmak na pasalubong at souvenir.
I guess if mas mababa ang budget nio, nde magagawa ang lahat or siguro, mas konting pasalubong lang. Pero relatively, Cebu and Bohol are not that expensive. Es[ecially since group naman kayo mag-travel. I still have the number of Tita Doris who arranged for our package tour in Bohol. I can send it to you if you want.
Hope it helped!
