Keep in mind also that the infrustructure in the beach communities, though developing, is not always reliable. We lose power several times a day, cell phones work about 50% of the time and internet is up and down. That being said, as the beach areas develop so will the infrustructure, which we are told (it is being upgraded) is why at present it is not reliable.
Dear Kent, try to be more specific if talking about beach communities, Jaco is not Costa Rica. I disagree with what you said, here on the beach in the Tamarindo we have a pretty stable power source and the cell phone service is reliable. We have power shortages sometimes yes but average without power like once a month for a total of 2 hours maybe. Both cell phone systems, the TDMA and the GSM work well, I would say 90% of the area is covered / with good-great signal. We have fast internet as well and it is fun surfing the internet.
Pura Vida
