Thanks to everyone for your thoughts. I am glad to see that I am not alone in thinking that longer sessions is where its at and going beyond 2 hours is probably where I am headed. The multi day sessions are intriguing but I don't think that is for me. I have been toying with the idea of doing an overnight session but I am not sure what to expect or if I could hold up for all that. Have any of you done overnighters? If so, any recommendations? I travel a lot for work and schedule my sessions for when I am out of town. Mainly on the west coast but I also get to Chicago and the NY area too and occasionally farther south and even Florida but so far I have limited my sessions to LA and NYC.
