Hello D.J., good to see you back here again!
Zona Blue: $46.00 U.S. cash with C.R.T. V.I.P. discount. The price is supposedly full service, but there have been numerous recent complaints about upselling and demands for tips (propinas) with some of the girls. It seems now that in addition to your $46.00, the girls expect tips ranging from $30 -40 paid in advance in order to give a heartfelt performance.
New Fantasy: Still $20.00 for a half hour, $36.00 for a full hour. Some girls recently have been reported to be getting a little tip-greedy.
Bar Idem.... don't ask. A ridiculous price increase last September has many CRT'ers foaming with rage. It's something like eighty bucks now... I don't know the exact price, I don't really care, it ain't my cup of chi.
Other MP's per RBC100's list, more or less.
Hope this helps. Kinda.
If you offered $10.00 to each of the two girls and they complained, keep in mind that your tip represented a generous 50% tip. 
I haven't used it, because frankly everytime I've gone in there I have been disappointed by the bad attitude of at least half the girls in there. And you know me, CC. You know I speak Spanish well, am clean and relaxed...a guy who would otherwise be thought of as a good client. I come in everytime with smiles...and leave frowning. Part of the reason for my dissatisfaction is the upselling and demands for propinas up front... and BTW, someone should explain to the girls that tips are paid *after* the session as a *reward* for good service, not paid in advance to "guarantee" good service. Work on that the next time you're in there, will you?
