I have researched many overseas programs before I selected this one, so I can tell you my reasons for choosing it. I specifically looked for a program with more health related concept than just general volunteer. I felt that many of the "volunteer" programs are more of touring than helping, but HLD is one that really need you to haul the cement (literally!). I also wanted to experience legitimate healthcare, not when they call stay-near-african-nursery-but-you-cant-go-in, a proper medical experience. And for discover, all I have to say is Juan and Jose knows where to party. You won't regret going to any of the towns they planned for you.
Here are the criteria of gooverseas.com, and I'll explain why each category I give its best.
Benefits: Worth. Two kinds of worth: what I paid for, and what I worked for to fund-raise before the trip. Not only the trip was fantastically done, fundraising to Gold Member is good deed for both the community and yourself too! HLD promised many GM benefits if you reach your fundraising goal, and you will definitely want all of them. Extra hour of surfing, GM trophy and goodies, and many more that will make the trip even better. Originally I was a bit hesitant paying 6k for the trip plus MP week, but after the trip I would give no hesitation to go back. As for fundraising experience, all your hard work will pay off throughout the trip and once you see the smiles of the families you will help.
Support: The leaders, guides and J+J makes sure you have been taken care of. A few times I've been left for a short while, but that is only because they have to take care of 40 other people too. You gotta understand that. During all three components of the trip, leaders and guides are with you. Never would you be left unsupported! I saw a comment about lack of communication before the trip, but that also depends on how anxious you will be. The leaders takes care of you starting from fundraising all the way to coming back.
Facilities: Would you expect good quality wifi in a third world country? I had to adjust my expectations before the trip, especially since the community you will be helping with most likely lack electricity completely, and clean water in general. Going on the trip reveal the amount of stuff I take for granted: too much. Don't expect hot water when you go volunteering, please. You will be experiencing the villager's lives, and they don't live with much that we do. That being said, your homebase hotel, as well as Discover travel hotels, are fully equipped with wifi and other amenities, enough bandwidth that I sneaked a game one latenight. (I apologize!) Many of them ARE all-inclusive hotel standard.
Fun: fun. much fun. fun day and night! Each location that I traveled, each piece of experience was filled with excitement and discovery. Absolutely nothing to regret.
Safety: There is not one point on the trip was I worried about safety. And I worry about safety when I can. Before the trip I was concerned with vaccines - please ensure you and your body is ready for the trip. Once that is done then there is nothing to worry.
I sincerely hope my comment will help settle any questions, and hope to see more HLD-ers out there!
