Yes, bring your own. The ONLY complaint I had was about the hairdryer. The cord is really short, it is one of the small attached to the wall kind The bathroom can stay a little humid of course, so its nice to be able to be mobile with your own dryer
I would say it depends on what kind of hair you have. I have very thick hair that is hard to dry, plus I style as I dry, so the dryers didn't work so well for me. I just bring my own now and I am assured better results.
You won't need an adapter. However, I recommend that you bring a power strip or an extension cord with more than one outlet at the end. I haven't been to CSA, but the outlet situation at CN is not terribly convenient.
