What an incredible trip! Gustavo was an amazing trip leader. He was organised, knowledgable, fun and always a step ahead of everyone. The itinerary is action packed and really allows you to to see the true Costa Rica and you have lots of fun along the way. You get enough breaks along the way and you're guaranteed to see lot of jungles, mountains, monkeys and plants.
If you're on the border line of booking, just do it! You won't regret it! It's the best Contiki trip that I've been on in the last few years!
