In 2005, I went with 3 first timers (my now DH, my sisters now DH and my dad), and my brother who had only been 6 the first and last time we went so it was like his first time. Maybe it was because we had a big group but...wow, was it stressful!
The men were sure they were going to find it cheesy and OTT (which they didn't!) amd everyone wanted to do their own thing. My sis and her DH wanted to shop first, my DH wanted to do the rides first, we couldn't get my dad to understand that he needed to walk just a little bit faster than snail's pace if he wanted to do all that he wanted to do...
In the end, we just broke off into groups, did our own thing and met up again for the parades and shows. But again, I couldn't get them to understand that they had to be at F! at least an hour before hand!
However, my very best memory is all of us sat together watching Spectromagic followed by Wishes. That was magical and something that DH and I relive every time we go back.
