Cortinas ... in Practica?

We have been thinking of whether or not to include cortinas in our Practica Otro ... We have currently set out the musics without cortinas but in tandas of 4 or 3 songs depending on the length of the songs, and we make all tandas with noticeable change of mood, like from tango to milonga, or tango to vals, or classical to nuevo ... so as to mark the change of tandas.

We've talked to friends who have different views of wanting or not wanting cortina ... here's some of the thoughts we have encountered ...

Views from different people :

... "i think it's better to have cortinas as sometime we don't know when to stop dancing, because we don't know the music well, and we are not able to count the number of songs which has been playing ... so, we don't know when to jump in and when to jump out ... "

... "i think it's better not to have cortinas because we want to keep practicing continuously, and there's no problem you jump in at the 3rd song of a tanda and leave at the 2nd song of the next tanda as when you think about something you want to practice, you can just jump in and move, you don't need to wait for the start of a tanda ... "

... " i want cortinas so that it's easier to say thank you to the partners if you want to stop dancing without any hard feelings ... if there's no cortinas, it seems there's not a common understanding of when to stop dancing, and if you say thank you, it seems that it mean you don't want to dance with him anymore ... and i'm afraid that they won't invite me again next time if i say thank you ... "

..."it's totally normal to say thank you to end the dances, we all need to learn to say thank you in a nice way and to accept a thank you without hard feelings ... that's how it works anywhere in the tango world ... "

... "All the practicas in Buenos Aires don't have cortinas, if we have cortinas, we are not keeping the tradition like in BsAs or other parts of the world, and it'll feels like a milonga rather than a practica again ... "

... " i think it's better to have cortinas, as in HK, there are more men than women, and many women want to grab a man to practice and they won't stop dancing with you even after 10 songs ... it's easier to change partners with the help of cortinas ..."

..." Practicas should have music ongoing, cortinas are for milongas where people stop for drinks and chat with friends and change partners to look for dates ... practicas are more for people who are really keen on improving their dancing ... not to relax and spend the nite ... "

... " i think for HK, it's better to have cortinas, as we're not like BsAs, where there are so many people dancing tango, and you'll meet different people in different milongas and practicas, so if you say thank you to someone when you don't want to dance with, you won't need to be afraid that they'll not invite you anymore as there are so many people in other milongas still, and you can choose whether you go to practica or milonga that night according to your mood ... but here, we meet the same bunch of people nearly in all milongas, and here we don't have a choice in one nite whether we go to practica or milonga ...
