Roa's Rapids is the name for the fast lazy river,which is awesome.The slow lazy river has a very strange entrance as there are two lines,one is to get the tubes to enter the lazy river and then get off to ride the bowl slides and the other line is to get the tubes to just go on the lazy river,they are different color tubes but the way this is set up seems to confuse half the people there,is it still set up like this or have they changed it from my last visit.The slow lazy river is also pretty short,it does have the aquarium areas which makes it pretty unique but aside from that being a short lazy river and having a strange line dillutes the quality of the attraction,Roa's Rapids is so cool however that it more than makes up for it.I think I spent like 3 hours in Roa's Rapids altogether.
