Well - Thanks again for everyone who has responded this far. Just an update. I have decided YES....to do the Red Centre!

Only thing I am trying to do now is find the ala carte way to see what I want to without any big tour thing...I like the on my own deals...so that is the next step. Should you have any info on how to get the ala carte sightseeing options by all means I will be listening.

Again thanks to all that have provided info.
