Hi Manuel! Welcome to planDisney!
I'm excited to hear about your upcoming visit to
Disney's Typhoon Lagoon Water Park! This is a family favorite of ours and one that we love to visit at least once during most stays.
From my experience riding
Miss Adventure Falls and the information provided on the Walt Disney World website, it seems that only four Guests are allowed to ride together on this attraction. A family of five will need to split up or take turns riding. While I'm sure this is the information you did not want to hear, Disney does need to ensure safety is taken into account for each attraction and capacities are met.
There are some awesome areas of this park that cater to younger Guests.
Ketchakiddee Creek is a kid-friendly area for Guests under 48 inches tall. There are mini waterslides, splash areas under a waterfall, and much more.
I also suggest checking out Gangplank Falls, which is similar to a white water rafting experience. It's designed for Guests of all heights, so your entire party should be able to ride. I'm unsure if you can all ride together, but you can always check with a Cast Member upon arrival.
Manuel, I hope you have a magical time during your stay!
Stop back and see us again at planDisney!
