Just wanted to add my dos colones to some things that have been said in regard to the explosion of eco tourism in Costa Rica. I put a resounding second to what El Ciego and Bilko have said.
As someone who fits both categories I perhaps have a somewhat different prospective of Costa Rica.
Costa Rica is the ONLY country in the world that doesn't spent a dime on a military industrial complex. It's taken the money they would have spent since 1949 and poured it into developing it's own natural resources. The government is constantly buying back the land from the robber barons of United Fruit and others. What we are left with is one of the most diverse ecological systems in the world and the only one in the western world.
Yes I'm a tree hugger and damn proud of it. I hug them, but I'm not into DFKing with them or tapping their bodily fluids
My point is that we have nothing to fear from the ecological visitors. They are truly the life blood of Costa Rica. With the exception of the African Palm tree plantations, a rather insignificant coffee production, and an even smaller banana industry, Costa Rica has no industry, no major exports, but exists solely due to the tourist trade (including us). If the government of Costa Rica decided to go the way of Brazil and cut down the trees, fouled the water, and destroyed their own envirnment you would soon discover that mongering was reduced to the level of Mexico's border towns.
We owe a lot to the tourists and rather than turning up our noses at them we should be thanking them for making Costa Rica a paradise for us.
El Ciego and Bilko pointed out that San Jose is little more than a transitory point enroute to the touristy parts of the country like Arenal, Monteverde, and Manuel Antonio. None of us are staying in those big expensive hotels out near the airport, they are being supported almost 100 by the tourists.
AM Costa Rica had an article several months back that said the average tourist spends less than a half day in San Jose. They fly in, meet their tourist buses and are on their way elsewhere. At the end of their trip they may take a few hours to hit the every popular Gold Museum and the National Theatre and then they are gone. The number one hotel is "central" San Jose is "Clarion's Amon Plaza." They probably have 20 tourist guest for every one at the El Presidente. (This according to a leading travel agency's booking service)
Is our collective ego so big that we really think these tourists give a shit about what we are doing ? Last year I spent at least 20 mornings having breakfast in El Presidente. Being a gregarious guy I struck up a lot of conversations with "Mr & Mrs Whitebread and the little Whitebreads" and found them delighted to be offered a little help with their planning. With "older" guys and young chica cuties surrounding us, I never heard one gringa mention the May-Dec relationships. I did hear several women comment about how cute our little chicas were.
When some of us think of tourists we think of the little blue haired ladies in tennis shoes scrambling around London, Berlin, and Tokyo.
Them days is gone my friends. Today's ecotourists are either tattooed, pierced hippie types (no offense meant to them either) on their way to the beach, or the average above middle class family who are on their way to see the volcanos, the birds, butterflies (and like me.........el monos

They could really give a shit less about who we are, and what we are doing in Costa Rica. Just a guess, but I'd say that the average US or Canadian knows that boys go to Thailand, Cambodia, and other asian destinations to screw young girls (or boys) but that reputation has not extended itself to Costa Rica and hopefully it won't.
I made whatever points I was trying to make and will now climb down from my soap box. Just remember, the Fer de Lance and the Bushmaster will never bother us if we don't bother them........the same goes for the ecotourist. I'm guessing that the new restrictions placed by the Presidente (many of them agreeably unfair) were put in place because some non-CRT members paraded drunk thru the lobby cursing and puking on the other guests. I want no part of those as__holes either.
Thanks for your time
