We did this with my 4 and 6 year old. The rafts have a seating place with an extra safety bar for a small child, so my youngest got that seat. They both loved the ride! Since my 4 year old was adamant that she not get her clothes wet, we brought her swimsuit and did a quick change for her in the restrooms. Afterwards she changed back to her dry clothes, which worked out great. BTW, she was too scared for Splash Mtn, but was not scared at all about Kali. No big mountain drop, no problem!
