I've been to disney like 35 times in my life so when I got this idea I knew i'd be comfortable with it, its almost like a second home to me.
My first time I was forced to do it while I was with family, so I took a low dose of LSD and it all worked out perfectly. It was beautiful, one of the funnest vacations i've ever had.
Second time I went alone and dose a bit higher, plugged in my headphones with the best of music and had a blast. Riding on space mountain with headphones in is the best thing ever. the total darkness lets your mind go wild.
Third time I took a tad too much, all the people just kind of freaked me out, and having no safe haven like a nearby hotel to go to kind of freaked me out as well, so I bailed and drove home.
So I still stick by that its a good idea, 2/3 times were AMAZING. Just make sure you don't take too high a dose, and its best if you are staying at a hotel near the park if you are going to take a really high dose, or don't be alone.
