Thanks David. I plan on doing plenty of exploring and photographing on my own - - with little sleep and am accustomed to that. However, I wanted to have a guide recommendation in my pocket in case I determine, it would be useful to find some more less traveled spots and to make sure I am in the right spot at right time for some sunrises. I have already amassed a great deal of material online and will plot out the "must sees" and "may sees" if time. I will likely take the "photo tour" to Spirit Island, as I have read some positive things about that, including that it simply gives you more time on the island to photograph. I will also likely purchase the e-book(s) I have read good things about, written by a photographer who's name escapes me at the moment.
