I've just received this question and I wonder if anyone has anything they can add on it.
Am looking for something to do over the Christmas & New Years break next year and was looking at a group out of New Zealand...

Looking at running down to Costa Rica for 4 weeks... 2-3 of it volunteering and a week + of running around and diving. Was thinking about doing the construction work in San Jose.
Curious if you or (someone you can point me to) can give me any feedback on the organization and/or if you are aware of and can recommend alternative organizations there or in Belize.
Started off looking for sea turtle conservation but then got to thinking that perhaps I ight be more useful/helpful doing something more up my own alley (15 years construction/15 years IT) - yeh only 42 but I grew up in the trades...
Just throwing this out there in case you have some insights.
