I have 5 trips under my belt, and each time I stayed between two and three weeks. I"m African-American and had no problems in costa rica, and to the contrary I found the the ticos and ticas to be extremely friendly towards me. I do speak a fair amount of spanish, and think that is best asset.
There are some of the ladies that are attracted more to black guys, and others that may shy away. I still think that the color green is the deciding factor to these ladies. I currently live in las vegas, and I would say that I am treated the same or better in costa rica or thailand.
My advice is to learn as much spanish as you can before your trip, and be prepared to have the time of your life. I may be there in late November for 10 days, so feel free to P.m. for info. Have a great time. The Crt'ers are also a great bunch of guys that will always help a brother out.
Other guys will disagree with this last point, but some of the bartenders will point you into the right direction of the sweet girls. Don't try to date the bartenders thou !!!
p.s. If you are a good dancer and can dance salsa, then you will need a bodyguard to keep the ladies off you. Latina's love to dance almost as much as the y love money. If you can take some salsa lesson before your trip, Then forget about!!
