Can anyone help me with paso doble counts at blackpool?

I mean, I have my routine for espana cani music, and I can do it in 8 counts to be applied to a regular (without highlights) music. But in blackpool, you can have espana cani, you can have music without highlights but not espana cani, and you can have multiple versions of espana cani.

How do you deal with that? You wait to listen to the type of music, or you just start in the beggining of the song and then see what you get?

It will be my first time in blackpool, and I´m a little bit affraid with the paso dobles

Thanks a lot for your help
