HELP..need advice quickly on Atlantis Sub

[lorriv20]

I just noticed this great weekly special on the Atlantis Sub ride in Cozumel

 

http://www.cozumelinsider.com/WeeklySpecial It is BOGO for adults and only costs $79.00 total for Sep. and Oct dates.

 

I would like to book it; however I have two questions:

 

Has anyone used this company before to purchase tickets?

 

and now the dumb question that I ask for medical reasons: Does anyone know if there is a bathroom on board the submarine?

 

I appreciate your help.
