Maybe around 2k but if I were you, I'd bring 10K for that. It should cover everything.
Usually, free ang driver and one passenger sa RORO but I have not tried Liloan to Surigao yet. Sa Misamis-Camiguin, 1k (peak season, off-800 ata), free two passengers. Civic FD. Bring a photocopy of your OR/CR and ID para derecho lahat.
