I enjoyed El Rio del Tiempo because it felt more authentic and genuine. TTC feels like putting lipstick on a pig to me personally.Personally, I like the Three Caballeros. I think it is an okay ride. However, I think that they should have kept El Rio del Tiempo. I love the Three Caballeros and wish they would have done more than just an overlay type ride.
It's an adequate ride if you're trying to avoid crowds at peak season, but I wouldn't go off the beaten path to seek it out.
