Internet-Wireless-Skype in Costa RicaManuel Antonio, La Fortuna, Montezuma, or Puerto Viejo as well. San Jose probably offers the cheapest prices as there’s lots of competition- often prices are as little as US$.50 an hour. In the more isolated areas prices can be much higher, since frequently a café may have little or no competition. Today, many hotels, even low-end hostels, offer free Internet service, and Spanish language schools will often provide free service to their students.
If you happen to be traveling with your own laptop, more and more hotels, resorts, airports, cafes, are going WI-FI (wireless), becoming ‘go to’ places that provide high-speed Internet access for free or perhaps a small charge for usage.
Having web access while traveling can also save a ton of money- by NOT having to make international calls using a credit card or regular phone. You should seriously consider a broadband-based telephone service such as Skype (http://www.skype.com), which enables you to make FREE or fairly inexpensive international calls over the internet. If you have an account, you can make calls from your own laptop, or from most internet cafes.
