Amazing day! Tortugas booked us on Tiburon Ballena. Omar and his mate took wonderful care of us. My boyfriend and I tagged along with a Mexcian couple from Cancun and a Spanish family from Barcelona. They were related I believe. They all spoke English and we were best friends by the end of the day. We got off to a late start, but it made for an great day. Omar took us out further than the local tour boats did. We got to a spot with so many Whale Sharks that I couldn't even count them. The only other boats that were with us were research boats and I think one or two other tour boats. It was a WS playground. After swimming with the sharks for a few hours, Omar took us out into the Caribbean Sea to a reef. We went snorkeling there for about an hour. Omar made us ceviche and fed us ham and cheese sandwiches. The tour included breakfast at Casa Las Tortugas and the amazing lunch that I just described. The tour took about 7hrs. I was worried that I was going to get sea sick, but I was fine. Omar provided me with Dramamine and I think that my adrenaline was pumping so hard from the sharks that I didn't have time to get sick. The tour cost 90$ US a person and we tipped Omar and his mate about $50 in toto. Highly suggest booking through Casa Las Tortugas even if you don't stay the hotel!
