Rob - The swells you may have experienced on the way back "up" to LA are very, very typical. Everyone who has done a Mex. Riv. cruise runs into those. It has to do with 2 currents diverging at the same spot. (I forgot the name of it, sorry.) Usually, going down to Mexico is a breeze, but coming back up isn't fun - at least for 1 day/night anyway. It kind of leaves a bad taste in your mouth when it happens at the end of your cruise. Try to remember the other, more calm days you had. Sounds like you didn't let it get to you though!
