I will be going to Rio for my 4th time Jan 27-feb 11th. Rented an appartment from ken at amerioca.net. Very nice guy. Does anyone have any information on what days and time are the best to visit the popular thermas (Luomo, 4x4, Solerium, centaurus, etc. A list of your favorite girls at each place would be great also. Anyone interested in hanging out in Rio end of Jan early February let me know. Mike

Every day, all of the time
or
try going on the early side (4) before they get too busy.

List of best girls? Forget it. They move too often, and one guy's 10/10 (attractiveness/session quality) is another guy's 7/6. Just wander in, see what appeals to you and go for it. There is such a thing as too much information. Go with your instincts.

I have never figured out why people call them thermas. It's termas, and it's pronounced that way as well - tehrrr-mah (s is optional on the end, IMHO)

Yes, termas, not to be confused with thermos. The "s" is optional in pronunciation but not in spelling. Termas is both the singular and plural form. Unlike thermos/thermoses.
