Tztexas!
Welcome, new friend. I'm glad you found CRT.
I think what will please you even more than the vast amount of useful and current info here will be the comraderie we share. If you're looking for guys to pal around with, you'll find them when you visit C.R.
Many (although not all!) SL guests will be CRT VIP's too, and you'll undoubtedly run into some goodfellas there. Also, guys typicaly gather at around 5:00 p.m. at the Blue Marlin for Happy Hour...check near the lobby or by the front windows across the street from the Monkey Bar to encounter other CRT'ers.

Just ask groups of guys sitting at the tables if they're CRT members.
Zona Blue...yes! But don't forget that there are numerous massage parlor options, and aside from New Fantasy and Bar Idem, they'll all be less expensive than Zona Blue. It might take longer to get there, and you may have to really search for that special hot lady, but you'll save money and get more variety...although nothing will match the Zona blue ambience, or that of Bar Idem.
Best of luck on your travels. If you have any questions and can't answer them by using the Search here, please feel free to post any questions. Your CRT bros. are here to help, con mucho gusto!
Again, welcome to the Internet's single best resource for gentleman travelers to Costa Rica!
Cheers,
Paul
