Great time and trip! Our guide Alejandro was amazing. My only “complaint “ is I wanted to tip him but there was no digital option. Give him a Venmo or QR code for tips.

Absolutely perfect!!! Exactly as promised. Guide, Victor, was a marine biologist and filled with knowledge about the wildlife and ocean life. He was so personable and friendly. The bioluminescence was a totally amazing phenomenon. Well worthwhile - great memories! Carole from Vancouver Canada
