I spent 10 days in AC during August, and it just so happened that we did 5 excursions with Searious. Altun Ha, Lamanai, Manatee trip, Mexico Rocks, and Hol Chan/Ray Alley.
Our guides were Ricky, Cool J, and Willie. They were all incredible, as were Sandy and the other woman in the office (forgot her name). They were very helpful in setting our days up, etc. and had some great wildlife sitings on all our excursions (crocodiles, iguanas, howlers, tarantulas, countless birds, snakes, baracuda, sharks, rays, starfish, moray eel...too many in the water to include.)
