Adonis already said pretty much what it´s all about. I will just add that for me NEST is mainly about THE PEOPLE! You will finally get to know lots of people who will understand you and be really nice with you. Being a newbie everyone will be proud of you for being able to be there and show yourself. Most of the time you can even move tickling to a second frame if you like it. It will always be there if you want to dig in, but you will also always have someone with whom to have a nice chat, just walk around, do silly stuff...whatever you enjoy most likely there will be someone around who also enjoys it.
So go for it if you can! And if it seems you really canot go....push yourself hard on this one, it´s worth the try!!!!!
I hope nothing will stop me from being there again! Hope to see Adonis, Brighteyes and Ann again, together with so many others we wont have enough time to name all of them here.
If I may, i´ll add just mi piece of advice, and i second Ann on this one: if you can, try to arrive early and tell someone you are doing that. I still remember the "night before" staying with the guys at the bar, having some beers and just having fun. We had stories from past NEST, teachings of what to expect on the next days, history lessons, tales from BDSM stuff, crash language trainings, amazing tales from dangerous border crossings...you name it we likely spoke of it that night.
So if you can, get there early! there will be someone around to hang up with
