Dissing casual plans on LSD because of your love to "be in the moment" is a little silly in my opinion. When I make plans for a trip, it's things like "Where would I WANNA start," or what types of plans should I make now that I know I'll be far too high to do later, because I know that I do not wanna spend 2 hours of my trip probably trying to plan something that takes 15 minutes sober -- I don't see what's completely wrong with that. I always obviously give myself the choice to curb all plans and do whatever, but some pre-stage planning, isn't necessarily a bad thing. It's not necessarily planning your trip, it's planning ahead so you can do nothing but trip. Get the friends you want involved (or plan for a solo trip). Pick one comfy place you don't mind spending the time at. Think of another place or two you think you'd may wanna check out, see if everyone else involved is cool "with the possibility" of that. Maybe bring some toys and music, see if you have any other fun sounding ideas and then drop and have fun.
