Altun Ha with Olde Belize River Tour--Help!!

Can anyone, please tell me which tour company offers Altun Ha with the river tour? I have been manoeuvring around sites, and now can't find the one I thought sounded pretty good. I'm getting dizzy clicking around all the cavetubing!

NCL offers it. Also try belizecruiseexcursions.com

Thanks! belizecruieseexcursions.com doesn't seem to have a river tour combined with Altun Ha.

Have never done ships excursions before, but am thinking to make an exception this time. Would be with NCL in Feb.
