They encourage you to bring someone with you to help you absorb all the info. I went alone and did fine. I could see the benefit of bringing someone if possible, but don't fret if you have to go alone - not a biggie. It's not like you'll be groggy or anything - it's just maybe a lot to absorb. Recommend bringing paper and pen to take notes (something I didn't think to do). AND - write your questions down before you go, and take them with you too.
