Awesome crew, very knowledgeable and friendly. The manta ray tour was incredible. The first night we didn't see any manta's (yeah, that happens sometimes in nature), but the crew gave us a refund in the form of another tour the next day. On that second day we saw around 6 huge manta rays, which was a magical experience. They swim up to 10 cm from your face, which is obviously pretty cool :) Small note: as the boat ride is on open sea, it's quite bumpy, make sure you take measures against motion sickness.
