we've done both...the catilina cruise is more days...and during the week I think...you should have done the zip line....pretty cool..the day at sea is worth the trip IMHO..we usally hang out at the Jacuzzi in the adult area..and the dance bar at night...kinda cool not hav'n to drive to dinner..but i'm like you ,.. couldn't do the long cruise...and all the ports are pretty much the same...
