there are two drops on KRR that i can recall....at the beginning after the long climbing build up....that drop is very small (but some people get soaked because of a geyser that goes off as you pass by)...that drop is probably the same as POC, if not smaller...
however, there is a bigger drop at the end of KRR.....however, it's really not much of a big deal (it's much much smaller than Splash, but bigger than POC...
the people who end up at the bottom of the raft as it gets to the bottom of that drop, get totally totally totally drenched...totally.....
this is a fun ride....and it has the disney storyline touches....we very much enjoy it.....and usually ride it several times in a row if the line permits....
please keep in mind that the bottom of the boat gets very wet....unless you're wearing water shoes/sandals, you should take them off and put them in the center holder...
and if you're wimps like us, you can also ride it wearing rain ponchos (be sure to tuck the poncho all around you and keep that hood up....you'll look stupid, but you'll stay dry)....
