I think Global Works does an amazing job connecting the kids with the community. My 2 kids (14 and 16) had fantastic homestay experiences and both of them still connect with their Costa Rica families every week, which has been a super cool experience.
I think global works is safe while at the same time creating some really great opportunities for kids to explore and challenge themselves. For example, the kids had the opportunity to attend a local city soccer team game and then ended up getting to play the city champions in an impromptu game which was a really neat experience. I also think it is good to really know that the kids really work hard for the community service - they are digging ditches, pouring concrete and clearing paths.
I think the big differentiator for Global Works is their connections with the community and providing an experience for kids to engage with groups of people that they would not have the opportunity to engage with on a more traditional tour - that connection is pretty special and results in some amazing opportunities. So, combine that with hard work and opportunities to explore the rainforest, zipline, and surf and it definitely is a unique experience.
